+## Task Tracking
+
+Project tasks live in Trello (imported from `trello-import.csv`).
+Before starting work, use the `trello` tool to check the board for the next
+pending card in priority order. When a task is complete, move its card to a
+"Done" list.
+
+Trello integration is configured via MCP in `opencode.json`. Requires
+`TRELLO_API_KEY` and `TRELLO_TOKEN` env vars (see `.env.example`).
