How is this wiki hosted?

This wiki is hosted by using gollum.

And also some other stuff:

• a bare git repository in the main users home directory
• a systemd service, which hosts gollum on localhost on port 8469
• an apache reverse proxy which enables SSL for this wiki

--no-edit means, that the wiki can only be edited by pushing new commits and not from the web interface. --emoji enables emoji rendering support, which is very important!
