----------------------
-

-
-The 3-digit-number will be tagged in the associated git repository as ``vX.Y.Z`` and the fully specified value can be found by running |git-describe|_ tool inside the correct git repository.
-
-.. |git-describe| replace:: ``git describe``
-.. _git-describe: https://git-scm.com/docs/git-describe
-
-The version number is broken down as ``vX.Y.Z-AAA-gHHHHH``;
-
-* The letter ``v``.
-
-* ``X`` = The "Milestone Release" Number
-
-  * **0** indicates **"alpha"** level. The IP has **not** undergone full qualification. Parts of the IP **may be immature and untested**.
-
-  * **1** indicates **"beta"** level. The IP has undergone qualification testing but has **not** been hardware verified.
-
-  * **2** indicates **production** level. The IP has passed qualification testing and has been hardware verified.
-
-* ``Y`` = The "Major Release" Number
-
-* ``Z`` = The "Minor Release" Number
-
-* A single hyphen character ``-``

-* ``AAA`` = The `git commit count <https://git-scm.com/docs/git-describe#_examples>`_ since the version number was tagged.
-
-* A single hyphen character followed by the letter g ``-g``
-
-* ``HHHH`` = A `git commit short hash <https://git-scm.com/book/en/v2/Git-Tools-Revision-Selection#_short_sha_1>`_ which uniquely identifies a specific git commit inside the associated git repository.
