+# Element Web - Matrix Client
+

+
+## Configuration
+
+The `config.json` file configures Element Web to connect to the local Synapse homeserver at `http://einszwovier.local:8008`.
+
+### Key Settings
+
+- **Homeserver**: Points to local Synapse instance
+- **Server name**: `einszwovier.local`
+- **Brand**: "studio einszwovier Chat"
+- **Default language**: German (DE)
+- **Default theme**: Light mode
+- **Guest access**: Enabled (users can preview without account)
+
+## Access
+
+- **URL**: `http://einszwovier.local:8082`
+- **No app required**: Works in any modern web browser
+- **Mobile friendly**: Responsive design works on phones and tablets
+
+## Usage
+
+1. Navigate to `http://einszwovier.local:8082`
+2. Click "Sign In" or "Create Account"
+3. Use existing Matrix credentials or create a new account
+4. Join rooms (e.g., the print order room)
+5. Chat, share files, and collaborate!
+
+## Features

+
+## Updates
+
+Element Web is managed by Watchtower and updates automatically with the rest of the stack.
+
+## Troubleshooting
+
+**Can't connect to homeserver:**
+
+- Ensure Synapse is running: `docker-compose ps synapse`
+- Check Synapse logs: `docker-compose logs synapse`
+- Verify hostname resolution: `ping einszwovier.local`
+
+**Login fails:**
+
+- Verify credentials with Matrix admin
+- Check Synapse registration settings in `matrix/data/homeserver.yaml`
+
+**Performance issues:**
+
+- Element Web is resource-intensive for large rooms
+- Consider using Hydrogen (lighter client) for low-end devices
+- Clear browser cache and reload
+
+## Security Notes
+
+- Element Web runs on HTTP in the local network
+- For production/internet exposure, configure HTTPS via reverse proxy
+- User sessions are stored in browser local storage
+- Encryption keys are managed client-side
