+Mosbot is a python program that tries to adjust our observing scripts
+to adapt to changing conditions through the night.
+
+Run it by logging in to the *mzls@mayall-idl* machine and then running:
+{{{
+cd ~/obsbot
+python mosbot.py <pass1.json> <pass2.json> <pass3.json>
+}}}
+you will need to keep that window open, because you want mosbot to keep running all night.
+"pass[123].json" are the 'plan' or 'JSON' files that Arjun should have given you;
+they contain lists of exposures we want to take depending on what the conditions are doing.
+It is probably most convenient to run mosbot from a Terminal window on the mayall-2 display.
+You don't need to read any of the output it produces, but you should check periodically
+that it is still running; the code is under development and some bugs remain.
+
+
+Mosbot does two things:
+
+1. On startup, it reads the *pass[123].json* files, drops exposures
+that should happen before the current time, for each exposure writes
+two little shell scripts, and also writes a top-level script
+*/mosaic3/exec/mosbot/tonight.sh*
+
+2. It then starts waiting for new images to appear in the $MOS3_DATA
+directory.  Whenever an image appears, it analyzes it and, based on
+the measured conditions (seeing, sky brightness, transparency), it
+decides which pass we should be running, and what our exposure times
+should be, and it overwrites the next few scripts.
