+# Contributing Guidelines
+
+## For New Contributors
+
+- Check the **good first issue** label for starter bugs & features.
+- Check **approved features** for features that have been approved by the dev team.
+
+## Workflow
+
+1. **Create or find issues.**
+2. **Message on the development channel** to discuss the feature you would like to implement.
+3. **Comment on the issue** asking to be assigned to it.
+4. **Create a PR**, wait for feedback.
+5. Once you've responded to feedback or pushed new commits, **re-request review** by clicking the ↻ icon next to the reviewer's name in the right sidebar.
+
+## PR Review Escalation
+
+If your PR has not been reviewed after a couple of days, escalate through these steps **in order**:
+
+1. Comment **"please review"** on the PR (this will refresh the PR and put it on top of the queue).
+2. Post a link to it in the development channel.
+3. Ping **@evan** in the development channel.
+
+## Important
+
+> **Please keep PRs small (<200 lines).** Some features may need to be split into multiple PRs.
