+#### Automatic PR Reviews
+
+Add opencode as a reviewer to automatically review PRs. When the `opencode` team is requested as a reviewer, the action will automatically trigger a comprehensive code review.
+
+To set this up:
+
+1. Create a team in your GitHub organization called `opencode`
+2. When creating or viewing a PR, add the `opencode` team as a reviewer
+3. The review workflow will automatically trigger and provide feedback
+
+This requires the review workflow file `.github/workflows/opencode-review.yml` to be present (created automatically by `opencode github install`).
+
 #### Review specific code lines
 
 Leave a comment directly on code lines in the PR's "Files" tab. opencode will automatically detect the file, line numbers, and diff context to provide precise responses.
