+### `openlama` launcher
+
+A convenience wrapper is installed at `~/.local/bin/openlama`. It sets `NO_PROXY`/`no_proxy` for localhost, tries to start `ollama-proxy` if it's down, and execs `opencode` with all forwarded args:
+
+```sh
+openlama                                   # TUI with ocp available as a provider
+openlama run -m ocp/gpt-oss:120b "hello"   # non-interactive, specific model
+```
+
 Run `/models` in the OpenCode TUI to pick a model from the pool, then chat as usual.
 
 ## Use with the `ollama` CLI
