 Older installs that still expose `claude-code-acp` are also supported. `buzz-acp`
 treats both Claude ACP command names as the same zero-arg runtime.
 
+## Running with Oh My Pi
+
+[Oh My Pi](https://omp.sh/) (`omp`) is a single-binary, multi-provider CLI whose ACP server is the `omp acp` subcommand — no separate adapter. It resolves its own model and credentials from `~/.omp`, so you authenticate omp once (e.g. an Anthropic Max subscription) and Buzz just spawns it.
+
+```bash
+# Install omp (see https://omp.sh/)
+curl -fsSL https://omp.sh/install.sh | bash
+
+# Authenticate a provider once (interactive), e.g. Anthropic Max:
+#   omp   # then run /login and pick Anthropic
+
+# Run
+export BUZZ_ACP_AGENT_COMMAND="omp"   # args default to `acp`
+
+buzz-acp
+```
+
+Select a model with `--model` in `BUZZ_ACP_AGENT_ARGS` (e.g. `acp,--model,claude-opus-4-5`) or set a default in `~/.omp/agent/config.yml`.
+
 ## Configuration
 
 All configuration is via environment variables (or CLI flags — every env var has a matching flag).

 > **Note — OpenClaw:** `openclaw acp` is a Gateway-backed bridge; PATH availability shows "Available" even when the OpenClaw Gateway daemon is not running. This is expected tier-2 semantics (same class as a preset with unconfigured auth). The Gateway URL is configured via `OPENCLAW_GATEWAY_URL` (or the equivalent env var from OpenClaw's docs) — set it in the agent's **env vars** in Edit Agent, not in the definition env (the preset definition carries no env entries). Note that `openclaw acp` executes tools inside the Gateway daemon, not the Desktop process, so Desktop-injected `BUZZ_*` env vars do NOT reach the execution locus unless you also set them on the Gateway's own environment.
