The Help tab lists the available documentation available for the user to read including this one as well as some information about the PCGen team. The available options are About and Docs.
The Docs option brings up the documentation web page stored under the /PCGen/docs directory on your computer. This is a all purpose document that allows the user to choose what type of documentation that you wish to use and a brief overview of each document that you can open and use.
The About option displays info about the release version/date of PCGen, as well as listing the main contributors. There are far too many contributors to list them all here since PCGen is very much a community effort. Info on where to get new releases of PCGen and how to find the PCGen community are also provided.
