Installing Homogram is more straightforward than what it could appear..
First, if you use Nginx as reversed proxy just point the root of your web app to /path/to/YourHomogram/Public/static
where the static content is located.
Apache instead should have DocumentRoot pointing to /path/to/YourHomogram/Public .
If you don't use Nginx as reversed proxy consider to merge /Public/static folder with /Public .
