+
+## Packages 
+
+Debian live stable configured with backports, the 'hibbian' repo and an LXDE
+desktop. It has every debian hamradio package (apart from svxlink, as that
+seizes audio and ruins things) and linbpq currently installed.
+
+It pulls the newest package either from the Debian repo or hibbian repo.
+
+## Persistence
+
+Persistence is enabled because I think it's the coolest thing. If you have an
+ext4 partition on any drive attached to the PC labelled 'persistence', you can
+ensure the system will use it to store data like updates, config files etc.
+
+It allows you to update the core system at a later date and start/stop the
+computer without losing data between restarts.

 # Caveat Emptor
 
 There are some caveats:
 
 ## Cache
 
-I run `apt-cacher-ng` on my system to keep packages required close. You may wish
-to do the same. If you do not, run remove the following line from `auto/config`: 
-`--apt-http-proxy http://127.0.0.1:3142`
+I run `apt-cacher-ng` on my system to keep packages required close. Instead of
+defining it here, I have a central config file for live-build that ensures I
+always do it. You may wish to do the same, it saves time.
+
+## Beta
+
+This is testing and I might migrate to KDE someday soon.
 
 That's it so far. More will appear no doubt.
