-======================
-= 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.

-=====================================================
-= Change Description / Commit Message / Patch Email =
-=====================================================
-
-Your change description should use the standard format for a
-commit message, and must include your "Signed-off-by" signature
-and the "Contributed-under" message.
-
-== Sample Change Description / Commit Message =
-
-=== Start of sample patch email message ===
-
-From: Contributor Name <contributor@example.com>
-Subject: [PATCH] CodeModule: Brief-single-line-summary
-
-Full-commit-message
-
-Contributed-under: TianoCore Contribution Agreement 1.0
-Signed-off-by: Contributor Name <contributor@example.com>
----
-
-An extra message for the patch email which will not be considered part
-of the commit message can be added here.
-
-Patch content inline or attached
-
-=== End of sample patch email message ===
-
-=== Notes for sample patch email ===
-
-* The first line of commit message is taken from the email's subject
-  line following [PATCH]. The remaining portion of the commit message
-  is the email's content until the '---' line.
-* git format-patch is one way to create this format
-
-=== Definitions for sample patch email ===
-
-* "CodeModule" is a short idenfier for the affected code.  For
-  example MdePkg, or MdeModulePkg UsbBusDxe.
-* "Brief-single-line-summary" is a short summary of the change.
-* The entire first line should be less than ~70 characters.
-* "Full-commit-message" a verbose multiple line comment describing
-  the change.  Each line should be less than ~70 characters.
-* "Contributed-under" explicitely states that the contribution is
-  made under the terms of the contribtion agreement.  This
-  agreement is included below in this document.
-* "Signed-off-by" is the contributor's signature identifying them
-  by their real/legal name and their email address.
