+# Synapse
+
+Synapse is the reference Matrix homeserver for self-hosted, federated, end-to-end encrypted messaging.
+
+## Dependencies
+
+- **PostgreSQL** - Database for storing messages and account data
+- **Redis** - Used for inter-worker communication
+
+## Configuration
+
+Key settings configured through your instance's `config.yaml`:
+
+- **domain** - Where the Synapse web client will be accessible (default: `synapse.{your-cloud-domain}`)
+- **serverName** - Your Matrix server identity, used in user IDs like `@user:{serverName}` (default: `{your-cloud-domain}`)
+- **enableRegistration** - Whether to allow public account creation (default: `false`)
+- **storage** - Persistent volume for Synapse data (default: `2Gi`)
+- **mediaStorage** - Persistent volume for uploaded media (default: `2Gi`)
+- **SMTP** - Email delivery settings inherited from your Wild Cloud instance
+
+## Access
+
+After deployment, the Synapse homeserver will be available at:
+- `https://synapse.{your-cloud-domain}`
+
+Connect using any Matrix client (Element, FluffyChat, etc.) with your server name.
+
+## First-Time Setup
+
+1. Add and deploy the app:
+   ```bash
+   wild app add synapse
+   wild app deploy synapse
+   ```
+
+2. Use the registration shared secret (in your `secrets.yaml`) to create your first admin account, or enable public registration temporarily
+
+3. Connect with a Matrix client and start messaging
