-= Code Contributions =
-======================
-
-To make a contribution to a TianoCore project, follow these steps.
-1. Create a change description in the format specified below to
-   use in the source control commit log.
-2. Your commit message must include your "Signed-off-by" signature,
-   and "Contributed-under" message.
-3. Your "Contributed-under" message explicitly states that the
-   contribution is made under the terms of the specified
-   contribution agreement.  Your "Contributed-under" message
-   must include the name of contribution agreement and version.
-   For example: Contributed-under: TianoCore Contribution Agreement 1.0
-   The "TianoCore Contribution Agreement" is included below in
-   this document.
-4. Submit your code to the TianoCore project using the process
-   that the project documents on its web page.  If the process is
-   not documented, then submit the code on development email list
-   for the project.
-5. It is preferred that contributions are submitted using the same
-   copyright license as the base project. When that is not possible,
-   then contributions using the following licenses can be accepted:
-   * BSD (2-clause): http://opensource.org/licenses/BSD-2-Clause
-   * BSD (3-clause): http://opensource.org/licenses/BSD-3-Clause
-   * MIT: http://opensource.org/licenses/MIT
-   * Python-2.0: http://opensource.org/licenses/Python-2.0
-   * Zlib: http://opensource.org/licenses/Zlib
-
-   Contributions of code put into the public domain can also be
-   accepted.
-
-   Contributions using other licenses might be accepted, but further
-   review will be required.
