 Super simple project management tool for developers.
 
 Born out of frustration with Jira.
+
+## Self hosting
+
+### Setup
+
+1. Copy `.env.example` files into `.env`:
+
+```bash
+cp packages/backend/.env.example packages/backend/.env
+cp packages/frontend/.env.example packages/frontend/.env
+```
+
+2. Backend `.env` required values:
+   - `DATABASE_URL`
+   - `JWT_SECRET`
+   - `RESEND_API_KEY` and `EMAIL_FROM` for verification emails
+   - `SEED_PASSWORD` if you plan to run `reset-and-seed`
+
+3. Frontend `.env` required values:
+   - `VITE_SERVER_URL`
+
+### Notes
+
+- OpenCode is optional. The app runs without it, but the AI helper requires OpenCode (no login needed).
+- S3 is optional. If you skip S3, image uploads will not work.
+- Stripe credentials are not needed for the current state.
+
+### Database seeding
+
+Run the seed script to create demo data:
+
+```bash
+bun reset-and-seed
+```
+
+This seeds demo issues, users, projects, and organisations. Demo users are created and can be used without verification emails. `SEED_PASSWORD` must be set in `packages/backend/.env`.
