 A naff IRC bot I rattled off in a hurry once, for folks stuck behind censor
 walls at work. Logs a channel and collects up all the URLs for later.
-
-Rewritten based on Twisted for now. One day they might port Twisted to Python 3.
-
+It was refactored for Twisted in 2011, then again to use pypi irc in 2015.
 Has recently grown a quiz feature based on MoxQuizz, which might actually turn
 into something useful one day.
+
+Installation
+------------
+
+To get started, set up a Python virtual environment, and install the stuff in
+`requirements.txt`.
+
+    apt-get install python-virtualenv
+
+Clone this git repository, and in the directory:
+
+    virtualenv env
+    env/bin/pip install -r requirements.txt
+
+Then you can run the bot like so:
+
+    env/bin/python lolbot.py <server[:port]> <channel> <nickname> <db>
+
+Development
+-----------
+
+Patches welcome! Development currently happens on the New Zealand Open Source
+Society [GitLab](https://git.nzoss.org.nz/moxquizz-fans/lolbot).
