+OBSERVATION SYSTEM SIMULATION EXPERIMENT
 
-OSSE is a configuration to simulate running an deterministic 
-ensemble Kalman filter on a rotating tank with an ice bucket 
-at the center.  
+OSSE is an MITgcm configuration to simulate data assimilation with a
+deterministic ensemble Kalman filter and a model of a rotating tank of
+water with an ice bucket at the center.
 
-code/ contains the modifications to MITgcm to run in cyclindrical
-coordinates.  At the time of this writing, it requires 
-checkpoint48 to compile and run.
+INSTALLATION 
 
-EnKF/ contains the source and data files to run the Kalman filter.
+At the time of this writing, the OSSE requires MITgcm checkpoint48 to
+compile and run.  MITgcm can be obtained from
+<http://mitgcm.org/source_code.html>.  If downloading from the CVS
+server, use the command
+
+cvs co -r 'checkpoint48' MITgcm
+
+in order to specify the correct version.  Read the instructions on the
+the webpage before trying to use the CVS server.
+
+The OSSE directory tree can be obtained from the MITgcm CVS repository
+with the command
+
+cvs co MITgcm_contrib/osse
+
+The code and its revision history can be browsed at 
+
+<http://dev.mitgcm.org/cgi-bin/viewcvs.cgi/MITgcm_contrib/osse/>
+
+A good place to put the osse directory tree is in MITgcm/verification,
+where examples and test examples of MITgcm configurations are kept.
