+# Odoo
+
+Odoo is a comprehensive open-source ERP and CRM suite covering accounting, sales, inventory, HR, project management, and more.
+
+## Dependencies
+
+- **PostgreSQL** - Database for storing all business data
+
+## Configuration
+
+Key settings in `config.yaml`:
+
+- **domain** - Where Odoo will be accessible
+- **storage** - Persistent volume size (default: `2Gi`)
+- **db.name** - Database name (default: `odoo`)
+
+## First-Time Setup
+
+1. Add and deploy the app:
+   ```bash
+   wild app add odoo
+   wild app deploy odoo
+   ```
+
+2. **First start takes 10–15 minutes** as Odoo installs the base module and runs all database migrations. The startup probe allows up to 20 minutes before failing.
+
+3. Once ready, log in with:
+   - **Email**: `admin`
+   - **Password**: value of `adminPassword` in your `secrets.yaml`
+
+4. The Odoo home menu will appear — install additional modules (Sales, Accounting, Inventory, etc.) from **Apps**.
+
+## Notes
+
+- The `adminPassword` in `secrets.yaml` is the **master password** for the Odoo database manager — this is separate from the `admin` user password, which is set during first boot using the same value
+- Odoo is started with `-d <db.name> -i base` to explicitly name the database and install the base module — this is required for the health check to pass
+- Each restart re-runs the base module check (idempotent) which adds a few seconds to startup time
