-= 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

-# Components Section - list of the modules and components that will be processed by compilation
-# tools and the EDK II tools to generate PE32/PE32+/Coff image files.
-#
-# Note: The EDK II DSC file is not used to specify how compiled binary images get placed
-# into firmware volume images. This section is just a list of modules to compile from
-# source into UEFI-compliant binaries.
-# It is the FDF file that contains information on combining binary files into firmware
-# volume images, whose concept is beyond UEFI and is described in PI specification.
-# Binary modules do not need to be listed in this section, as they should be
-# specified in the FDF file. For example: Shell binary (Shell_Full.efi), FAT binary (Fat.efi),
-# Logo (Logo.bmp), and etc.
-# There may also be modules listed in this section that are not required in the FDF file,
-# When a module listed here is excluded from FDF file, then UEFI-compliant binary will be
-# generated for it, but the binary will not be put into any firmware volume.
