+Quick usage:
+
+```bash
+# build image (from repo root)
+docker build -t repos:latest .
+
+# run help
+docker run --rm repos:latest
+
+# run PR command (ensure token passed)
+docker run --rm
+  -e GITHUB_TOKEN="$GITHUB_TOKEN" \
+  repos:latest pr --title "fix: update config" --body "Detailed description"

+Tip: mount host workspace if operations need local files:
+`docker run --rm -v "$(pwd):/work" -w /work -e GITHUB_TOKEN="$GITHUB_TOKEN" repos:latest run "ls -la"`
