 5.  **Run the development server:**
+
     ```bash
     yarn dev
     ```
+
     Open [http://localhost:3000](http://localhost:3000) in your browser to see the application.

 **Self-Hosting with Docker (Planned):**
 
 - A Docker image and `docker-compose.yml` file will be provided in the future to allow for easy self-hosting of the MeetUP application. This setup will also include database services. Instructions will be updated here once available.
