For step 6: update index.php, it is not clear to me how to update the index.php file with the code snippet. Do I add it at the beginning of the file? After the tag? At the end of the file?
Is there some step missing? The last steps are cloning a repo and modifying some configurations ( creating the .env file and modifying index.php). After cloning the repo there is no step to start an app, or restart a service or anything like that.
