+### Backend URL
+
+The frontend backend URL can be configured using the `SYNBIOHUB_BACKEND` environment variable. If not set, it defaults to `http://localhost:7777`.
+
+To use a custom backend URL, you can set it when starting Docker Compose:
+
+```bash
+SYNBIOHUB_BACKEND=http://your-backend-url:port docker-compose -f ./docker-compose.yml up
+```
+
+Alternatively, you can create a `.env` file in the same directory as `docker-compose.yml`:
+
+```bash
+cp .env.example .env
+# Edit .env and uncomment/set SYNBIOHUB_BACKEND
+docker-compose -f ./docker-compose.yml up
+```
+
