HRepo is my own APT repository for hosting my programs and some others, that are sometimes not available from the distro's default repo. These softwares include Skype, Opera, WPS Office, Discord, Lutris and so on.

As a user you've nothing to do with this, except adding it to your system with this simple command:

curl -L | bash

As a developer, feel free to look into it, so maybe it can help you to understand how APT repositories work.

If you have any problems / requests / questions feel free to provide feedback.
