+### TODO Workflow
+
+**Policy:**  
+From now on, the only thing to be committed directly to the `master` branch will be to-do items (.md files in `todo/queued/`).
+
+**Process:**  
+1. When deciding to work on a to-do item: create a branch, implement on the branch, submit PR to `master`.  
+2. After PR merge: move the item to `todo/completed/`.
+
+**Example workflow:**  
+```bash
+git checkout -b feature/some-todo
+# Implement changes, test with make test lint
+git add .
+git commit -m "feat: implement some-todo"
+git push -u origin feature/some-todo
+# Create and merge PR to master
+
+# Post-merge:
+git checkout master
+git pull
+mv "todo/queued/SOME_TODO.md" "todo/completed/SOME_TODO.md"
+git add todo/
+git commit -m "chore: complete some-todo"
+git push origin master
+```
