-So you want to start up dalek?  Ok.
-
-1. Log into hack.p6c.org under account dalek.  moritz will add your ssh key
-   there if you ask.
-
-2. 'tmux attach' or 'tmux', whichever works.  'screen' would work too, but I
-   prefer tmux.
-
-3. Start the 2 parts of dalek in separate windows:
-
-3a: The IRC component:
-    cd ~/dalek; while true; do perl botnix --debug; sleep 30; done
-
-3b: The HTTP stub for receiving push notifications:
-    cd ~/dalek/dalek-poller; starman --listen :8088 push.psgi
-
-4. Detach and log out.
