-## Self-Hosted Sync Server
-
-You can run your own sync server to keep your data in sync across devices. The server is lightweight and easy to set up using Docker.
-
-### Quick Start with Docker Compose
-
-1. Create a `.env` file with your configuration:
-```
-IMAGE=git.atri.dad/atridad/ascently-sync:latest
-APP_PORT=8080
-AUTH_TOKEN=your-secure-auth-token-here
-DATA_FILE=/data/ascently.json
-IMAGES_DIR=/data/images
-ROOT_DIR=./ascently-data
-```
-
-2. Use the provided `docker-compose.yml` in the `sync/` directory:
-```bash
-cd sync/
-docker-compose up -d
-```
-
-The server will be available at `http://localhost:8080`. Configure your clients with your server URL and auth token to start syncing.
+Documentation can be found at [https://ascently.atri.dad](https://ascently.atri.dad)!
