+# P4Ruby
 P4Ruby is a wrapper for the P4 C++ API in Ruby.
+
+P4Ruby is a Ruby module that provides an object-oriented API to Helix Core server. Using P4Ruby is faster than using the command-line interface in scripts, because multiple command can be executed on a single connection, and because it returns Helix server responses as Ruby hashes and arrays.
+
+## Requirements
+For P4Ruby requirements see "Compatibility Statements" in [RELNOTES](https://github.com/perforce/p4ruby/blob/master/RELNOTES.txt#L99)
+
+## Documentation
+Official documentation is located on the [Perforce website](https://www.perforce.com/manuals/p4ruby/Content/P4Ruby/Home-p4ruby.html)
+
+## Support
+P4Ruby is officially supported by Perforce.
+Pull requests will be managed by Perforce's engineering teams. We will do our best to acknowledge these in a timely manner based on available capacity.  
+Issues will not be managed on GitHub. All issues should be recorded via [Perforce's standard support process](https://www.perforce.com/support/request-support).
