+### Using BarnOwl
+You will need access to an Athena machine to run barnowl. The easiest
+way to do this would be to SSH into linux.mit.edu.
+
+On a Debian-based linux distro, open up a terminal and type `ssh
+<username>@linux.mit.edu`.
+
+On Windows, download a SSH client (such as
+[PuTTY](http://chiark.greenend.org.uk/~sgtatham/putty/download.html); you will need to [change PuTTY’s character set](http://utf-8.scripts.mit.edu/wiki/PuTTY) to UTF-8 to prevent occasional display glitches.)
+and install it. Once you've opened it, type `<username>@linux.mit.edu`
+into the prompt and hit enter.
+
+On a Mac, open Terminal from the Utilities Folder in Applications. Type
+`kinit <username>@ATHENA.MIT.EDU && ssh -K
+<username>@linux.mit.edu` If this command fails (saying -K is
+invalid), then just do `ssh <username>@linux.mit.edu`.
+
+Alternatively, use a Java applet called Mindterm SSH inside any web browser. MIT makes this available at [athena.dialup.mit.edu](http://athena.dialup.mit.edu/ssh.html); although this will give you an Athena terminal, you may want to ssh from there to linux.mit.edu so as to follow the rest of these instructions exactly:
+
+ athena.dialup.mit.edu login: <username>
+ <username>@athena.dialup.mit.edu's password: <password>
+ (wait a while)
+ <username>@<some-server>:~$ ssh <username>@linux.mit.edu
+ <username>@<other-server>:~$
+
+(In all these cases, don't include the angle brackets, just replace
+<username> with your MIT username). You will then be prompted for your
+password. Enter it, and then carry on with running barnowl!
