+# PicoClaw — Personal AI Agent Stack
+#
+# PicoClaw is an open-source personal AI assistant (Go, MIT).
+# Repo: https://github.com/sipeed/picoclaw
+#
+# The launcher container provides:
+#   - Web UI (picoclaw-launcher) on port 18800 — configure agents, channels, etc.
+#   - Gateway HTTP server on port 18790 — webhook endpoint for chat channels
+#
+# The editor (VS Code, ttyd, etc.) is chosen separately in the dashboard
+# and injected into the tools container.
+#
+# First boot: open the web UI endpoint and run `picoclaw onboard`
+# in the terminal to configure your API key, then restart the workspace.
