When using GitCentric, the documentation you need depends on what component you are using:
The AccuRev Installation and Release Notes are available from the Micro Focus Product Documentation page here: http://supportline.microfocus.com/productdoc.aspx
Because GitCentric spans the environments of AccuRev, Git, and Gerrit Code Review, you may encounter some conflicts or overlaps in terminology. For example, Gerrit Code Review often uses the term project to refer to a repository. AccuRev uses the terms repository or repo when referring to a repository, and reserves the term project for referring to specific Gerrit Code Review functionality, or when referring to some kind of planned or defined undertaking. See Glossary for definitions of terms used in GitCentric.
