+This directory contains PDF versions of the Quick Start Guide and Parts 1 and 2 of Hazy, 
+the documentation. This Quick Start Guide gives an overview.  Part 1 gives a complete 
+list of all commands.  Part 2 describes the output that is generated, shows how to extract observed quantities from the predictions, and explains how to call Cloudy as part 
+of a larger program. 
+
+Part 3, which is badly out of date at the time of this writing, describes
+the physics behind the simulation.  The past few years have seen many
+expansions of the code's capabilities, especially in infrared emission,
+molecular physics, dynamics and advective flows, and time dependent simulations.
+Unfortunately, Part 3 of Hazy has not had a high enough
+priority to be updated with available resources.  I have not given up and
+do intend to update this section eventually.  For now, an ADS search on
+"Ferland, G" will find the most recent papers that describe advances in the
+physics.
+
+The LaTeX source needed to build the documentation is included in \cdFilename{cloudy/docs/latex}.
+The Perl script \cdFilename{CompileAll.pl} will compile all four parts of the documentation,
+leaving PDF files in the appropriate subdirectories.
