 ## Running the project
 
 Once the project is build, run the command below. Replace `<application_id>` and `<project_name>` with the values you entered during project creation. Please note that these commands are just for demonstration purposes. Normally this would be handled by your IDE, such as GNOME Builder or VS Code with the Flatpak extension.
