+
+== Why? ==
+
+{{{screen}}} is a handy tool.  It lets you get more out of a terminal session, whether in a window, via ssh, or by some more esoteric means.
+It's original reason for existence was allowing you to switch between subsessions on a [http://en.wikipedia.org/wiki/Video_terminal video-display terminal],
+but grew to allow sessions that could be detached and reattached (if you went home for the day, or say you were connecting via a glitchy network) and eventually
+to allow the same session to be simultaneously accessed from multiple places.
+
+== Getting Started ==
+
+1.  Pick a machine to run your screen session on.  If you don't know of any options, linux.mit.edu (Linerva) is a good choice.
+2.  ssh to that machine.
+3.  run {{{screen}}}
+4.  Do stuff.
+
+To detach, type "C-a d".  To reattach, type {{{screen -dr}}}
+
+If you close your ssh connection without detaching, or lose your network connection.
+
+1.  run {{{screen -dr}}}
+2.  Do stuff.
+
+Once you're comfortable with this, hit "C-a C-c".  This creates what screen calls a new "window"; it should give you a new shell prompt,
+and you can do stuff at it.  If you want to switch back to the old "window", hit "C-a C-a".   You can create as many "windows" as you want;  you can
+switch to the first 10 of them with "C-a 0" through "C-a 9" and see a list of what's open with "C-a w".
