+perl-tutorial.org base
+======================
+
+This repository contains the actual wiki contents and some styling of the site
+http://perl-tutorial.org
+
+Changes in here are automatically synched to the server whenever the wiki
+software is prompted to rebuild, meaning either:
+
+- `ikiwiki -setup ~/PerlTutorialHub.setup` is executed on the server
+- an admin user goes into `Preferences > Setup` and clicks `Save`
+- a page is edited (not entirely sure about this yet)
+
+Additionally any changes done on the wiki will be pushed to this repo. It is
+the actual database used by the wiki software to store page contents.
+
+So, if you do not like web interfaces too much, you can just push to this repo
+and do any of the above to get your changes online. If you find that you are not
+able to do what you desire, feel free to swing by in IRC or contact any of the
+people on the [perl-tutorial contact page](http://perl-tutorial.org/contact/) to
+get the changes online, an admin flag or your ssh key onto the server.
