+# GitHub Actions created PR open/closer
+
+This automation triggers an automatic close & reopen on PRs opened by the
+`github-actions` user, i.e., from a GitHub actions job. This enables CI to run
+on those PRs without needing a manual poke from some human.
+
+## Configuration
+
+This feature is enabled on a repository by having a `[bot-pull-requests]` table in `triagebot.toml`:
+
+```toml
+[bot-pull-requests]
+```
+
+## Implementation
+
+See [`src/handlers/bot_pull_requests.rs`](https://github.com/rust-lang/triagebot/blob/HEAD/src/handlers/bot_pull_requests.rs).
