You can use the Admin-panel to manage your plugins and install new ones.

The plugins' "online directory" is GitHub. Each author is responsible for its own.

When installed, a plug-in is just a folder inside "plugins" folder.

Manual installation

Under the hood, installing a plugin just means copying its folder inside plugins folder. Deleting that folder will uninstall it.

If the name of the folder ends with -disabled, HFS will just ignore it.

Online directory

This is where HFS finds plugins online: https://github.com/search?q=topic%3Ahfs-plugin&type=repositories

If you decide to download and install manually from there, the only thing you have to copy is the "dist" folder, but remember to rename it with the name of the plugin itself, otherwise HFS will present any plugin as "dist".

For authors
