+Documentation for starting an online compact binary coalescence analysis
+========================================================================
+
+Prerequisites
+-------------
+
+ - Fully functional gstlal, gstlal-ugly, gstlal-inspiral installation
+ - Condor managed computing resource with dedicated nodes to support online jobs (which run indefinitely)
+ - Network streaming gravitational wave data
+
+Introduction
+------------
+
+FIXME add more
+
+The online analysis has a somewhat involved setup procedure.  This
+documentation covers all of it. The steps are:
+
+ 1. Generate template banks for the target search area
+ 2. Decompose the template waveforms using the SVD in chirpmass and chi bins
+ 3. Setup and run the actual online analysis.
+
+You can expect the setup (steps 1 and 2) to take several days.  Furthermore,
+the analsysis (step 3) requires at minimum several days of burn-in time until
+it learns the noise statistics of the data before it should be allowed to
+submit candidate gravitational waves.  Plan accordingly.
+
+**Note, this tutorial will assume a specific directory structure and certain
+configuration files.  These can and should be changed by the user.  This
+tutorial should be considered to be a guide, not cut-and-paste instructions.**
