-Provider packages
------------------
 
-Airflow 2.0 is split into core and providers. They are delivered as separate packages:
+Airflow dependencies
+--------------------
+
+Airflow is not a standard python project. Most of the python projects fall into one of two types -
+application or library. As described in
+[StackOverflow Question](https://stackoverflow.com/questions/28509481/should-i-pin-my-python-dependencies-versions)
+decision whether to pin (freeze) requirements for a python project depdends on the type. For
+applications, dependencies should be pinned, but for libraries, they should be open.
+
+For application, pinning the dependencies makes it more stable to install in the future - because new
+(even transitive) dependencies might cause installation to fail. For libraries - the dependencies should
+be open to allow several different libraries with the same requirements to be installed at the same time.
+
+The problem is that Apache Airflow is a bit of both - application to install and library to be used when
+you are developing your own operators and DAGs.
+
+This - seemingly unsolvable - puzzle is solved by having pinned requirement files. Those are available
+as of airflow 1.10.10.
+
+Pinned requirement files
+------------------------
+
+By default when you install ``apache-airflow`` package - the dependencies are as open as possible while
+still allowing the apache-airflow package to install. This means that 'apache-airflow' package might fail to
+install in case a direct or transitive dependency is released that breaks the installation. In such case
+when installing ``apache-airflow``, you might need to provide additional constraints (for
+example ``pip install apache-airflow==1.10.2 Werkzeug<1.0.0``)
+
+However we now have ``requirements-python<PYTHON_MAJOR_MINOR_VERSION>.txt`` file generated
+automatically and committed in the requirements folder based on the set of all latest working and tested
+requirement versions. Those ``requirement-python<PYTHON_MAJOR_MINOR_VERSION>.txt`` files can be used as
+constraints file when installing Apache Airflow - either from the sources
+
+.. code-block:: bash
+
+  pip install -e . --constraint requirements/requirements-python3.6.txt
+
+
+or from the pypi package
+
+.. code-block:: bash
+
+  pip install apache-airflow --constraint requirements/requirements-python3.6.txt
+
+
+This works also with extras - for example:
+
+.. code-block:: bash
 
-* ``apache-airflow`` - core of Apache Airflow
-* ``apache-airflow-providers-*`` - More than 50 provider packages to communicate with external services
+  pip install .[ssh] --constraint requirements/requirements-python3.6.txt
+
+
+It is also possible to use constraints directly from github using tag/version name:
+
+.. code-block:: bash
 
-In Airflow 1.10 all those providers were installed together within one single package and when you installed
-airflow locally, from sources, they were also installed. In Airflow 2.0, providers are separated out,
-and not packaged together with the core, unless you set ``INSTALL_PROVIDERS_FROM_SOURCES`` environment
-variable to ``true``.
+  pip install apache-airflow[ssh]==1.10.10 \
+      --constraint https://raw.githubusercontent.com/apache/airflow/1.10.10/requirements/requirements-python3.6.txt
 
-In Breeze - which is a development environment, ``INSTALL_PROVIDERS_FROM_SOURCES`` variable is set to true,
-but you can add ``--skip-installing-airflow-providers-from-sources`` flag to Breeze to skip installing providers when
-building the images.
+There are different set of fixed requirements for different python major/minor versions and you should
+use the right requirements file for the right python version.
 
-One watch-out - providers are still always installed (or rather available) if you install airflow from
-sources using ``-e`` (or ``--editable``) flag. In such case airflow is read directly from the sources
-without copying airflow packages to the usual installation location, and since 'providers' folder is
-in this airflow folder - the providers package is importable.
+The ``requirements-python<PYTHON_MAJOR_MINOR_VERSION>.txt`` file MUST be regenerated every time after
+the ``setup.py`` is updated. This is checked automatically in the CI build. There are separate
+jobs for each python version that checks if the requirements should be updated.
+
+If they are not updated, you should regenerate the requirements locally using Breeze as described below.
+
+Generating requirement files
+----------------------------
+
+This should be done every time after you modify setup.py file. You can generate requirement files
+using `Breeze <BREEZE.rst>`_ . Simply use those commands:
+
+.. code-block:: bash
+
+  breeze generate-requirements --python 3.7
+
+.. code-block:: bash
+
+  breeze generate-requirements --python 3.6
+
+Note that when you generate requirements this way, you might update to latest version of requirements
+that were released since the last time so during tests you might get errors unrelated to your change.
+In this case the easiest way to fix it is to limit the culprit dependency to the previous version
+with ``<NNNN.NN>`` constraint added in setup.py.
+
+Backport providers packages
+---------------------------
+
+Since we are developing new operators in the master branch, we prepared backport packages ready to be
+installed for Airflow 1.10.* series. Those backport operators (the tested ones) are going to be released
+in PyPi and we are going to maintain the list at
+`Backported providers package page <https://cwiki.apache.org/confluence/display/AIRFLOW/Backported+providers+packages+for+Airflow+1.10.*+series>`_
 
 Some of the packages have cross-dependencies with other providers packages. This typically happens for
 transfer operators where operators use hooks from the other providers in case they are transferring
 data between the providers. The list of dependencies is maintained (automatically with pre-commits)
 in the ``airflow/providers/dependencies.json``. Pre-commits are also used to generate dependencies.
-The dependency list is automatically used during PyPI packages generation.
+The dependency list is automatically used during pypi packages generation.
 
 Cross-dependencies between provider packages are converted into extras - if you need functionality from

-How to sync your fork
-=====================
+Contribution Workflow Example
+==============================
 
-When you have your fork, you should periodically synchronize the master of your fork with the
-Apache Airflow master. In order to do that you can ``git pull --rebase`` to your local git repository from
-apache remote and push the master (often with ``--force`` to your fork). There is also an easy
-way using ``Force sync master from apache/airflow`` workflow. You can go to "Actions" in your repository and
-choose the workflow and manually trigger the workflow using "Run workflow" command.
+Typically, you start your first contribution by reviewing open tickets
+at `GitHub issues <https://github.com/apache/airflow/issues>`__.
 
-This will force-push the master from apache/airflow to the master in your fork. Note that in case you
-modified the master in your fork, you might loose those changes.
+If you create pull-request, you don't have to create an issue first, but if you want, you can do it.
+Creating an issue will allow you to collect feedback or share plans with other people.
 
+For example, you want to have the following sample ticket assigned to you:
+`#7782: Add extra CC: to the emails sent by Aiflow <https://github.com/apache/airflow/issues/7782>`_.
 
-How to rebase PR
-================
+In general, your contribution includes the following stages:
 
-A lot of people are unfamiliar with the rebase workflow in Git, but we think it is an excellent workflow,
-providing a better alternative to the merge workflow. We've therefore written a short guide for those who would like to learn it.
+.. image:: images/workflow.png
+    :align: center
+    :alt: Contribution Workflow
 
-As opposed to the merge workflow, the rebase workflow allows us to
-clearly separate your changes from the changes of others. It puts the responsibility of rebasing on the
-author of the change. It also produces a "single-line" series of commits on the master branch. This
-makes it easier to understand what was going on and to find reasons for problems (it is especially
-useful for "bisecting" when looking for a commit that introduced some bugs).
+1. Make your own `fork <https://help.github.com/en/github/getting-started-with-github/fork-a-repo>`__ of
+   the Apache Airflow `main repository <https://github.com/apache/airflow>`__.
 
-First of all, we suggest you read about the rebase workflow here:
-`Merging vs. rebasing <https://www.atlassian.com/git/tutorials/merging-vs-rebasing>`_. This is an
-excellent article that describes all the ins/outs of the rebase workflow. I recommend keeping it for future reference.
+2. Create a `local virtualenv <LOCAL_VIRTUALENV.rst>`_,
+   initialize the `Breeze environment <BREEZE.rst>`__, and
+   install `pre-commit framework <STATIC_CODE_CHECKS.rst#pre-commit-hooks>`__.
+   If you want to add more changes in the future, set up your fork and enable Github Actions.
 
-The goal of rebasing your PR on top of ``apache/master`` is to "transplant" your change on top of
-the latest changes that are merged by others. It also allows you to fix all the conflicts
-that arise as a result of other people changing the same files as you and merging the changes to ``apache/master``.
+3. Join `devlist <https://lists.apache.org/list.html?dev@airflow.apache.org>`__
+   and set up a `Slack account <https://apache-airflow-slack.herokuapp.com>`__.
 
-Here is how rebase looks in practice (you can find a summary below these detailed steps):
+4. Make the change and create a `Pull Request from your fork <https://help.github.com/en/github/collaborating-with-issues-and-pull-requests/creating-a-pull-request-from-a-fork>`__.
 
-1. You first need to add the Apache project remote to your git repository. This is only necessary once,
-so if it's not the first time you are following this tutorial you can skip this step. In this example,

+Step 1: Fork the Apache Repo
+----------------------------
+From the `apache/airflow <https://github.com/apache/airflow>`_ repo,
+`create a fork <https://help.github.com/en/github/getting-started-with-github/fork-a-repo>`_:
 
-2. You then need to make sure that you have the latest master fetched from the ``apache`` repository. You can do this
-   via:
+.. image:: images/fork.png
+    :align: center
+    :alt: Creating a fork
 
-   ``git fetch apache`` (to fetch apache remote)
 
-   ``git fetch --all``  (to fetch all remotes)
+Step 2: Configure Your Environment
+----------------------------------
+Configure the Docker-based Breeze development environment and run tests.
 
-3. Assuming that your feature is in a branch in your repository called ``my-branch`` you can easily check
-   what is the base commit you should rebase from by:
+You can use the default Breeze configuration as follows:
 
-   ``git merge-base my-branch apache/master``
+1. Install the latest versions of the Docker Community Edition
+   and Docker Compose and add them to the PATH.
 
-   This will print the HASH of the base commit which you should use to rebase your feature from.
-   For example: ``5abce471e0690c6b8d06ca25685b0845c5fd270f``. Copy that HASH and go to the next step.
+2. Enter Breeze: ``./breeze``
 
-   Optionally, if you want better control you can also find this commit hash manually.
+   Breeze starts with downloading the Airflow CI image from
+   the Docker Hub and installing all required dependencies.
 
-   Run:
+3. Enter the Docker environment and mount your local sources
+   to make them immediately visible in the environment.
 
-   ``git log``
+4. Create a local virtualenv, for example:
 
-   And find the first commit that you DO NOT want to "transplant".
+.. code-block:: bash
 
-   Performing:
+   mkvirtualenv myenv --python=python3.6
 
-   ``git rebase HASH``
+5. Initialize the created environment:
 
-   Will "transplant" all commits after the commit with the HASH.
+.. code-block:: bash
 
-4. Providing that you weren't already working on your branch, check out your feature branch locally via:
+   ./breeze --initialize-local-virtualenv
 
-   ``git checkout my-branch``
+6. Open your IDE (for example, PyCharm) and select the virtualenv you created
+   as the project's default virtualenv in your IDE.

-   There are various tools that can help you with this. You can use:
+- `Issues on GitHub <https://github.com/apache/airflow/issues>`__
 
-   ``git mergetool``
+- `Slack (chat) <https://apache-airflow-slack.herokuapp.com/>`__
 
-   You can configure different merge tools with it. You can also use IntelliJ/PyCharm's excellent merge tool.
-   When you open a project in PyCharm which has conflicts, you can go to VCS > Git > Resolve Conflicts and there
-   you have a very intuitive and helpful merge tool. For more information, see
-   `Resolve conflicts <https://www.jetbrains.com/help/idea/resolving-conflicts.html>`_.
+Step 4: Prepare PR
+------------------
 
-8. After you've solved your conflict run:
+1. Update the local sources to address the issue.
+
+   For example, to address this example issue, do the following:
 
-   ``git rebase --continue``
+   * Read about `email configuration in Airflow <https://airflow.readthedocs.io/en/latest/howto/email-config.html>`__.
 
-   And go either to point 6. or 7, depending on whether you have more commits that cause conflicts in your PR (rebasing applies each
-   commit from your PR one-by-one).
+   * Find the class you should modify. For the example ticket,
+     this is `email.py <https://github.com/apache/airflow/blob/master/airflow/utils/email.py>`__.
+
+   * Find the test class where you should add tests. For the example ticket,
+     this is `test_email.py <https://github.com/apache/airflow/blob/master/tests/utils/test_email.py>`__.
 
-Summary
--------------
+   * Create a local branch for your development. Make sure to use latest
+     ``apache/master`` as base for the branch. See `How to Rebase PR <#how-to-rebase-pr>`_ for some details
+     on setting up the ``apache`` remote. Note - some people develop their changes directy in their own
+     ``master`` branches - this is OK and you can make PR from your master to ``apache/master`` but we
+     recommend to always create a local branch for your development. This allows you to easily compare
+     changes, have several changes that you work on at the same time and many more.
+     If you have ``apache`` set as remote then you can make sure that you have latest changes in your master
+     by ``git pull apache master`` when you are in the local ``master`` branch. If you have conflicts and
+     want to override your locally changed master you can override your local changes with
+     ``git fetch apache; git reset --hard apache/master``.
 
-Useful when you understand the flow but don't remember the steps and want a quick reference.
+   * Modify the class and add necessary code and unit tests.
+
+   * Run the unit tests from the `IDE <TESTING.rst#running-unit-tests-from-ide>`__
+     or `local virtualenv <TESTING.rst#running-unit-tests-from-local-virtualenv>`__ as you see fit.
+
+   * Run the tests in `Breeze <TESTING.rst#running-unit-tests-inside-breeze>`__.
+
+   * Run and fix all the `static checks <STATIC_CODE_CHECKS>`__. If you have
+     `pre-commits installed <STATIC_CODE_CHECKS.rst#pre-commit-hooks>`__,
+     this step is automatically run while you are committing your code. If not, you can do it manually
+     via ``git add`` and then ``pre-commit run``.
+
+2. Rebase your fork, squash commits, and resolve all conflicts. See `How to rebase PR <#how-to-rebase-pr>`_
+   if you need help with rebasing your change. Remember to rebase often if your PR takes a lot of time to
+   review/fix. This will make rebase process much easier and less painful - and the more often you do it,
+   the more comfortable you will feel doing it.
+
+3. Re-run static code checks again.
+
+4. Create a pull request with the following title for the sample ticket:
+   ``[AIRFLOW-5934] Added extra CC: field to the Airflow emails.``
+
+Make sure to follow other PR guidelines described in `this document <#pull-request-guidelines>`_.
+
+
+Step 5: Pass PR Review
+----------------------

+when merging PRs and your commit will be squashed to single commit.
+
+How to rebase PR
+================
+
+A lot of people are unfamiliar with rebase workflow in Git, but we think it is an excellent workflow,
+much better than merge workflow, so here is a short guide for those who would like to learn it. It's really
+worth to spend a few minutes learning it. As opposed to merge workflow, the rebase workflow allows to
+clearly separate your changes from changes of others, puts responsibility of proper rebase on the
+author of the change. It also produces a "single-line" series of commits in master branch which
+makes it much easier to understand what was going on and to find reasons for problems (it is especially
+useful for "bisecting" when looking for a commit that introduced some bugs.
+
+
+First of all - you can read about rebase workflow here:
+`Merging vs. rebasing <https://www.atlassian.com/git/tutorials/merging-vs-rebasing>`_ - this is an
+excellent article that describes all ins/outs of rebase. I recommend reading it and keeping it as reference.
+
+The goal of rebasing your PR on top of ``apache/master`` is to "transplant" your change on top of
+the latest changes that are merged by others. It also allows you to fix all the conflicts
+that are result of other people changing the same files as you and merging the changes to ``apache/master``.
+
+Here is how rebase looks in practice:
+
+1. You need to add Apache remote to your git repository. You can add it as "apache" remote so that
+   you can refer to it easily:
+
+``git remote add apache git@github.com:apache/airflow.git`` if you use ssh or
+``git remote add apache https://github.com/apache/airflow.git`` if you use https.
+
+Later on
+
+2. You need to make sure that you have the latest master fetched from ``apache`` repository. You can do it
+   by ``git fetch apache`` for apache remote or ``git fetch --all`` to fetch all remotes.
+
+3. Assuming that your feature is in a branch in your repository called ``my-branch`` you can check easily
+   what is the base commit you should rebase from by: ``git merge-base my-branch apache/master``.
+   This will print the HASH of the base commit which you should use to rebase your feature from -
+   for example: ``5abce471e0690c6b8d06ca25685b0845c5fd270f``. You can also find this commit hash manually -
+   if you want better control. Run ``git log`` and find the first commit that you DO NOT want to "transplant".
+   ``git rebase HASH`` will "trasplant" all commits after the commit with the HASH.
+
+4. Make sure you checked out your branch locally:
 
-``git fetch --all``
-``git merge-base my-branch apache/master``
 ``git checkout my-branch``
-``git rebase HASH --onto apache/master``
-``git push --force-with-lease``
+
+5. Rebase:
+   Run: ``git rebase HASH --onto apache/master``
+   for example: ``git rebase 5abce471e0690c6b8d06ca25685b0845c5fd270f --onto apache/master``
+
+6. If you have no conflicts - that's cool. You rebased. You can now run ``git push --force-with-lease`` to
+   push your changes to your repository. That should trigger the build in our CI if you have a
+   Pull Request opened already.
+
+7. While rebasing you might have conflicts. Read carefully what git tells you when it prints information
+   about the conflicts. You need to solve the conflicts manually. This is sometimes the most difficult
+   part and requires deliberate correcting your code looking what has changed since you developed your
+   changes. There are various tools that can help you with that. You can use ``git mergetool`` (and you can
+   configure different merge tools with it). Also you can use IntelliJ/PyCharm excellent merge tool.
+   When you open project in PyCharm which has conflict you can go to VCS->Git->Resolve Conflicts and there
+   you have a very intuitive and helpful merge tool. You can see more information
+   about it in `Resolve conflicts <https://www.jetbrains.com/help/idea/resolving-conflicts.html.>`_
+
+8. After you solved conflicts simply run ``git rebase --continue`` and go either to point 6. or 7.
+   above depending if you have more commits that cause conflicts in your PR (rebasing applies each
+   commit from your PR one-by-one).

+Azure Blob Storage Transfer Operator
+====================================
+The Blob service stores text and binary data as objects in the cloud.
+The Blob service offers the following three resources: the storage account, containers, and blobs.
+Within your storage account, containers provide a way to organize sets of blobs.
+For more information about the service visit `Azure Blob Storage API documentation <https://docs.microsoft.com/en-us/rest/api/storageservices/blob-service-rest-api>`_.
+
+Before you begin
+^^^^^^^^^^^^^^^^
+Before using Blob Storage within Airflow you need to authenticate your account with Token, Login and Password.
+Please follow Azure
+`instructions <https://docs.microsoft.com/en-us/azure/storage/common/storage-account-keys-manage?tabs=azure-portal>`_
+to do it.

+Airflow dependencies
+====================
+
+.. note::
+
+   On November 2020, new version of PIP (20.3) has been released with a new, 2020 resolver. This resolver
+   might work with Apache Airflow as of 20.3.3, but it might lead to errors in installation. It might
+   depend on your choice of extras. In order to install Airflow you might need to either downgrade
+   pip to version 20.2.4 ``pip install --upgrade pip==20.2.4`` or, in case you use Pip 20.3,
+   you need to add option ``--use-deprecated legacy-resolver`` to your pip install command.
+
+   While ``pip 20.3.3`` solved most of the ``teething`` problems of 20.3, this note will remain here until we
+   set ``pip 20.3`` as official version in our CI pipeline where we are testing the installation as well.
+   Due to those constraints, only ``pip`` installation is currently officially supported.

+   `pip-tools <https://pypi.org/project/pip-tools/>`_, they do not share the same workflow as
+   ``pip`` - especially when it comes to constraint vs. requirements management.
+   Installing via ``Poetry`` or ``pip-tools`` is not currently supported.
+
+   If you wish to install airflow using those tools you should use the constraint files and convert
+   them to appropriate format and workflow that your tool requires.

-Airflow dependencies
---------------------
-
-Airflow is not a standard python project. Most of the python projects fall into one of two types -
-application or library. As described in
-[StackOverflow Question](https://stackoverflow.com/questions/28509481/should-i-pin-my-python-dependencies-versions)
-decision whether to pin (freeze) requirements for a python project depdends on the type. For
-applications, dependencies should be pinned, but for libraries, they should be open.
-
-For application, pinning the dependencies makes it more stable to install in the future - because new
-(even transitive) dependencies might cause installation to fail. For libraries - the dependencies should
-be open to allow several different libraries with the same requirements to be installed at the same time.
-
-The problem is that Apache Airflow is a bit of both - application to install and library to be used when
-you are developing your own operators and DAGs.
-
-This - seemingly unsolvable - puzzle is solved by having pinned requirement files. Those are available
-as of airflow 1.10.10.
-
-Pinned requirement files
-------------------------
-
-By default when you install ``apache-airflow`` package - the dependencies are as open as possible while
-still allowing the apache-airflow package to install. This means that 'apache-airflow' package might fail to
-install in case a direct or transitive dependency is released that breaks the installation. In such case
-when installing ``apache-airflow``, you might need to provide additional constraints (for
-example ``pip install apache-airflow==1.10.2 Werkzeug<1.0.0``)
-
-However we now have ``requirements-python<PYTHON_MAJOR_MINOR_VERSION>.txt`` file generated
-automatically and committed in the requirements folder based on the set of all latest working and tested
-requirement versions. Those ``requirement-python<PYTHON_MAJOR_MINOR_VERSION>.txt`` files can be used as
-constraints file when installing Apache Airflow - either from the sources
-
-.. code-block:: bash
-
-  pip install -e . --constraint requirements/requirements-python3.6.txt
-
-
-or from the pypi package
-
-.. code-block:: bash
-
-  pip install apache-airflow --constraint requirements/requirements-python3.6.txt
-
-
-This works also with extras - for example:
-
-.. code-block:: bash
+Airflow 2.0 is split into core and providers. They are delivered as separate packages:
 
-  pip install .[ssh] --constraint requirements/requirements-python3.6.txt
-
-
-It is also possible to use constraints directly from github using tag/version name:
-
-.. code-block:: bash
+* ``apache-airflow`` - core of Apache Airflow
+* ``apache-airflow-providers-*`` - More than 50 provider packages to communicate with external services
 
-  pip install apache-airflow[ssh]==1.10.10 \
-      --constraint https://raw.githubusercontent.com/apache/airflow/1.10.10/requirements/requirements-python3.6.txt
+In Airflow 1.10 all those providers were installed together within one single package and when you installed
+airflow locally, from sources, they were also installed. In Airflow 2.0, providers are separated out,
+and not packaged together with the core, unless you set ``INSTALL_PROVIDERS_FROM_SOURCES`` environment
+variable to ``true``.
 
-There are different set of fixed requirements for different python major/minor versions and you should
-use the right requirements file for the right python version.
+In Breeze - which is a development environment, ``INSTALL_PROVIDERS_FROM_SOURCES`` variable is set to true,
+but you can add ``--skip-installing-airflow-providers-from-sources`` flag to Breeze to skip installing providers when
+building the images.
 
-The ``requirements-python<PYTHON_MAJOR_MINOR_VERSION>.txt`` file MUST be regenerated every time after
-the ``setup.py`` is updated. This is checked automatically in the CI build. There are separate
-jobs for each python version that checks if the requirements should be updated.
-
-If they are not updated, you should regenerate the requirements locally using Breeze as described below.
-
-Generating requirement files
-----------------------------
-
-This should be done every time after you modify setup.py file. You can generate requirement files
-using `Breeze <BREEZE.rst>`_ . Simply use those commands:
-
-.. code-block:: bash
-
-  breeze generate-requirements --python 3.7
-
-.. code-block:: bash
-
-  breeze generate-requirements --python 3.6
-
-Note that when you generate requirements this way, you might update to latest version of requirements
-that were released since the last time so during tests you might get errors unrelated to your change.
-In this case the easiest way to fix it is to limit the culprit dependency to the previous version
-with ``<NNNN.NN>`` constraint added in setup.py.
-
-Backport providers packages
----------------------------
-
-Since we are developing new operators in the master branch, we prepared backport packages ready to be
-installed for Airflow 1.10.* series. Those backport operators (the tested ones) are going to be released
-in PyPi and we are going to maintain the list at
-`Backported providers package page <https://cwiki.apache.org/confluence/display/AIRFLOW/Backported+providers+packages+for+Airflow+1.10.*+series>`_
+One watch-out - providers are still always installed (or rather available) if you install airflow from
+sources using ``-e`` (or ``--editable``) flag. In such case airflow is read directly from the sources
+without copying airflow packages to the usual installation location, and since 'providers' folder is
+in this airflow folder - the providers package is importable.
 
 Some of the packages have cross-dependencies with other providers packages. This typically happens for
 transfer operators where operators use hooks from the other providers in case they are transferring
 data between the providers. The list of dependencies is maintained (automatically with pre-commits)
 in the ``airflow/providers/dependencies.json``. Pre-commits are also used to generate dependencies.
-The dependency list is automatically used during pypi packages generation.
+The dependency list is automatically used during PyPI packages generation.
 
 Cross-dependencies between provider packages are converted into extras - if you need functionality from

-Contribution Workflow Example
-==============================
-
-Typically, you start your first contribution by reviewing open tickets
-at `GitHub issues <https://github.com/apache/airflow/issues>`__.
-
-If you create pull-request, you don't have to create an issue first, but if you want, you can do it.
-Creating an issue will allow you to collect feedback or share plans with other people.
-
-For example, you want to have the following sample ticket assigned to you:
-`#7782: Add extra CC: to the emails sent by Aiflow <https://github.com/apache/airflow/issues/7782>`_.
-
-In general, your contribution includes the following stages:
-
-.. image:: images/workflow.png
-    :align: center
-    :alt: Contribution Workflow
-
-1. Make your own `fork <https://help.github.com/en/github/getting-started-with-github/fork-a-repo>`__ of
-   the Apache Airflow `main repository <https://github.com/apache/airflow>`__.
-
-2. Create a `local virtualenv <LOCAL_VIRTUALENV.rst>`_,
-   initialize the `Breeze environment <BREEZE.rst>`__, and
-   install `pre-commit framework <STATIC_CODE_CHECKS.rst#pre-commit-hooks>`__.
-   If you want to add more changes in the future, set up your fork and enable Github Actions.
-
-3. Join `devlist <https://lists.apache.org/list.html?dev@airflow.apache.org>`__
-   and set up a `Slack account <https://apache-airflow-slack.herokuapp.com>`__.
-
-4. Make the change and create a `Pull Request from your fork <https://help.github.com/en/github/collaborating-with-issues-and-pull-requests/creating-a-pull-request-from-a-fork>`__.
-
-5. Ping @ #development slack, comment @people. Be annoying. Be considerate.
-
-Step 1: Fork the Apache Repo
-----------------------------
-From the `apache/airflow <https://github.com/apache/airflow>`_ repo,
-`create a fork <https://help.github.com/en/github/getting-started-with-github/fork-a-repo>`_:
-
-.. image:: images/fork.png
-    :align: center
-    :alt: Creating a fork
-
-
-Step 2: Configure Your Environment
-----------------------------------
-Configure the Docker-based Breeze development environment and run tests.
-
-You can use the default Breeze configuration as follows:
-
-1. Install the latest versions of the Docker Community Edition
-   and Docker Compose and add them to the PATH.
-
-2. Enter Breeze: ``./breeze``
-
-   Breeze starts with downloading the Airflow CI image from
-   the Docker Hub and installing all required dependencies.
-
-3. Enter the Docker environment and mount your local sources
-   to make them immediately visible in the environment.
-
-4. Create a local virtualenv, for example:
-
-.. code-block:: bash
-
-   mkvirtualenv myenv --python=python3.6
-
-5. Initialize the created environment:
-
-.. code-block:: bash
-
-   ./breeze --initialize-local-virtualenv
+How to sync your fork
+=====================
 
-6. Open your IDE (for example, PyCharm) and select the virtualenv you created
-   as the project's default virtualenv in your IDE.
+When you have your fork, you should periodically synchronize the master of your fork with the
+Apache Airflow master. In order to do that you can ``git pull --rebase`` to your local git repository from
+apache remote and push the master (often with ``--force`` to your fork). There is also an easy
+way using ``Force sync master from apache/airflow`` workflow. You can go to "Actions" in your repository and
+choose the workflow and manually trigger the workflow using "Run workflow" command.
 
-Step 3: Connect with People
----------------------------
+This will force-push the master from apache/airflow to the master in your fork. Note that in case you
+modified the master in your fork, you might loose those changes.
 
-For effective collaboration, make sure to join the following Airflow groups:

+How to rebase PR
+================
 
-  - Developer’s mailing list `<dev-subscribe@airflow.apache.org>`_
-    (quite substantial traffic on this list)
+A lot of people are unfamiliar with the rebase workflow in Git, but we think it is an excellent workflow,
+providing a better alternative to the merge workflow. We've therefore written a short guide for those who would like to learn it.
 
-  - All commits mailing list: `<commits-subscribe@airflow.apache.org>`_
-    (very high traffic on this list)
+As opposed to the merge workflow, the rebase workflow allows us to
+clearly separate your changes from the changes of others. It puts the responsibility of rebasing on the
+author of the change. It also produces a "single-line" series of commits on the master branch. This
+makes it easier to understand what was going on and to find reasons for problems (it is especially
+useful for "bisecting" when looking for a commit that introduced some bugs).
 
-  - Airflow users mailing list: `<users-subscribe@airflow.apache.org>`_
-    (reasonably small traffic on this list)
+First of all, we suggest you read about the rebase workflow here:
+`Merging vs. rebasing <https://www.atlassian.com/git/tutorials/merging-vs-rebasing>`_. This is an
+excellent article that describes all the ins/outs of the rebase workflow. I recommend keeping it for future reference.
 
-- `Issues on GitHub <https://github.com/apache/airflow/issues>`__
+The goal of rebasing your PR on top of ``apache/master`` is to "transplant" your change on top of
+the latest changes that are merged by others. It also allows you to fix all the conflicts
+that arise as a result of other people changing the same files as you and merging the changes to ``apache/master``.
 
-- `Slack (chat) <https://apache-airflow-slack.herokuapp.com/>`__
+Here is how rebase looks in practice (you can find a summary below these detailed steps):
 
-Step 4: Prepare PR
-------------------
+1. You first need to add the Apache project remote to your git repository. This is only necessary once,
+so if it's not the first time you are following this tutorial you can skip this step. In this example,
+we will be adding the remote
+as "apache" so you can refer to it easily:
 
-1. Update the local sources to address the issue.
+* If you use ssh: ``git remote add apache git@github.com:apache/airflow.git``
+* If you use https: ``git remote add apache https://github.com/apache/airflow.git``
 
-   For example, to address this example issue, do the following:
+2. You then need to make sure that you have the latest master fetched from the ``apache`` repository. You can do this
+   via:
 
-   * Read about `email configuration in Airflow <https://airflow.readthedocs.io/en/latest/howto/email-config.html>`__.
+   ``git fetch apache`` (to fetch apache remote)
 
-   * Find the class you should modify. For the example ticket,
-     this is `email.py <https://github.com/apache/airflow/blob/master/airflow/utils/email.py>`__.
+   ``git fetch --all``  (to fetch all remotes)
 
-   * Find the test class where you should add tests. For the example ticket,
-     this is `test_email.py <https://github.com/apache/airflow/blob/master/tests/utils/test_email.py>`__.
+3. Assuming that your feature is in a branch in your repository called ``my-branch`` you can easily check
+   what is the base commit you should rebase from by:
 
-   * Create a local branch for your development. Make sure to use latest
-     ``apache/master`` as base for the branch. See `How to Rebase PR <#how-to-rebase-pr>`_ for some details
-     on setting up the ``apache`` remote. Note - some people develop their changes directy in their own
-     ``master`` branches - this is OK and you can make PR from your master to ``apache/master`` but we
-     recommend to always create a local branch for your development. This allows you to easily compare
-     changes, have several changes that you work on at the same time and many more.
-     If you have ``apache`` set as remote then you can make sure that you have latest changes in your master
-     by ``git pull apache master`` when you are in the local ``master`` branch. If you have conflicts and
-     want to override your locally changed master you can override your local changes with
-     ``git fetch apache; git reset --hard apache/master``.
+   ``git merge-base my-branch apache/master``
 
-   * Modify the class and add necessary code and unit tests.
+   This will print the HASH of the base commit which you should use to rebase your feature from.
+   For example: ``5abce471e0690c6b8d06ca25685b0845c5fd270f``. Copy that HASH and go to the next step.
 
-   * Run the unit tests from the `IDE <TESTING.rst#running-unit-tests-from-ide>`__
-     or `local virtualenv <TESTING.rst#running-unit-tests-from-local-virtualenv>`__ as you see fit.
+   Optionally, if you want better control you can also find this commit hash manually.
 
-   * Run the tests in `Breeze <TESTING.rst#running-unit-tests-inside-breeze>`__.
+   Run:
 
-   * Run and fix all the `static checks <STATIC_CODE_CHECKS>`__. If you have
-     `pre-commits installed <STATIC_CODE_CHECKS.rst#pre-commit-hooks>`__,
-     this step is automatically run while you are committing your code. If not, you can do it manually
-     via ``git add`` and then ``pre-commit run``.
+   ``git log``
 
-2. Rebase your fork, squash commits, and resolve all conflicts. See `How to rebase PR <#how-to-rebase-pr>`_
-   if you need help with rebasing your change. Remember to rebase often if your PR takes a lot of time to
-   review/fix. This will make rebase process much easier and less painful - and the more often you do it,
-   the more comfortable you will feel doing it.
+   And find the first commit that you DO NOT want to "transplant".
 
-3. Re-run static code checks again.
+   Performing:
 
-4. Create a pull request with the following title for the sample ticket:
-   ``[AIRFLOW-5934] Added extra CC: field to the Airflow emails.``
+   ``git rebase HASH``
 
-Make sure to follow other PR guidelines described in `this document <#pull-request-guidelines>`_.
+   Will "transplant" all commits after the commit with the HASH.
 
+4. Providing that you weren't already working on your branch, check out your feature branch locally via:
 
-Step 5: Pass PR Review
-----------------------
+   ``git checkout my-branch``
 
-.. image:: images/review.png
-    :align: center
-    :alt: PR Review
+5. Rebase:
 
-Note that committers will use **Squash and Merge** instead of **Rebase and Merge**
-when merging PRs and your commit will be squashed to single commit.
+   ``git rebase HASH --onto apache/master``

+Commit Policy
+=============
+
+The following commit policy passed by a vote 8(binding FOR) to 0 against on May 27, 2016 on the dev list
+and slightly modified and consensus reached in October 2020:
+
+* Commits need a +1 vote from a committer who is not the author
+* Do not merge a PR that regresses linting or does not pass CI tests (unless we have
+  justification such as clearly transient error).
+* When we do AIP voting, both PMC and committer +1s are considered as binding vote.
