 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 Kimi Code
+
+[Kimi Code](https://moonshotai.github.io/kimi-code/) exposes a native ACP
+server and reuses the login saved by its CLI:
+
+```bash
+# Install Kimi Code using the official platform-specific installer, then:
+kimi login
+
+export BUZZ_ACP_AGENT_COMMAND="kimi"
+export BUZZ_ACP_AGENT_ARGS="acp"
+
+buzz-acp
+```
+
+Buzz Desktop also includes Kimi Code in its preset runtime catalog. The
+standalone installer's `~/.kimi-code/bin` directory is probed directly so a
+GUI-launched desktop process can find `kimi` even when it inherited a stale
+`PATH`.
+
 ## Configuration
 
 All configuration is via environment variables (or CLI flags — every env var has a matching flag).
