+or an existing AST object.

 ## Usage
 
-Here is a list of example that are typical use cases for the module.
-
-### Example 1: Get the function name from a script
+The commands accept a file path (`-Path`) or inline script content (`-Script`), and default to matching everything so
+you can narrow the results with `-Name`.
 
-This example shows how to get the function name from a script.
+### Example: List the functions defined in a script
 
 ```powershell
-Get-AstFunctionName -Path 'Test-Me.ps1'
-Test-Me
+Get-AstFunction -Path ./MyScript.ps1
+Get-AstFunctionName -Path ./MyScript.ps1
 ```
