-This Git repository is a tip migration of a subversion repository which has our history going back about fifteen years. The subversion repository is maintained as a read-only reference at
-https://viewvc.nublado.org          or
-https://trac.nublado.org/browser 
-
-The migration was done on 2020 Dec2 at r14364.  Only the trunk and a few actively maintained branches were migrated.

README.md

+# Cloudy
+
+Cloudy is an _ab initio_ spectral synthesis code designed to model a wide range
+of interstellar "clouds", from H II regions and planetary nebulae, to Active
+Galactic Nuclei, and the hot intracluster medium that permeates galaxy clusters.
+
+Cloudy has been in continuous development since 1978, led by Gary Ferland, and
+in close collaboration with a number of scientists -- see the
+[list of contributors](others.txt).
+
+
+# Version
+
+The current version of Cloudy is C22, released in Fall 2022.
+A summary of what is new is available
+[here](https://gitlab.nublado.org/cloudy/cloudy/-/wikis/NewC22).
+
+## Brief History
+
+Cloudy recently migrated to a pure git version control system from a
+subversion (SVN) system (with limited support for git).
+Cloudy had been on a SVN repository for about 15 years, which is still 
+maintained as a read-only reference at
+[https://viewvc.nublado.org](https://viewvc.nublado.org) or
+[https://trac.nublado.org/browser](https://trac.nublado.org/browser).
+
+The migration was done on 2020 Dec 2 at r14364.
+Only the trunk and a few actively maintained branches were migrated.
+
+Previous releases of Cloudy are still available on the SVN site,
+as well as tarballs on our
+[release folder](https://data.nublado.org/cloudy_releases).
+
+
+# API
+
+Cloudy's API is described with [Doxygen](https://doxygen.nl), and is available
+[online](https://data.nublado.org/doxygen/c22.00).
+
+
+# Contact us
+
+See the project's [website](https://nublado.org) for new versions, bug fixes,
+etc.
+
+If you have any questions, please post them on the
+[Cloudy user group](https://cloudyastrophysics.groups.io/g/Main/topics).
