+## Git and PR Workflow
+
+### Commit Messages
+- Start with the Jira ticket reference: `OLS-XXXX description`
+- Keep the first line under 72 characters
+- Use imperative mood
+
+### Pull Requests
+This repo uses a **fork-based workflow**:
+
+1. **Push to your fork**, not to `origin` (openshift/lightspeed-operator)
+2. **Create the PR** against `origin/main` using your fork's branch:
+   ```bash
+   git push <your-fork-remote> <branch>
+   gh pr create --repo openshift/lightspeed-operator --head <your-github-user>:<branch> --base main
+   ```
+3. **PR title** must start with the Jira reference: `OLS-XXXX description`
+4. **Squash commits** before pushing -- one logical commit per PR unless the PR explicitly tracks multiple independent changes
+
+### Branch Completion
+When finishing a development branch:
+1. Remove any process artifacts (design docs, plans in `docs/superpowers/`)
+2. Squash commits with the Jira-prefixed message
+3. Push to the contributor's fork remote (not `origin`)
+4. Create the PR against `origin/main` using `--head <user>:<branch>`
