+# 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
+
+```
+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
+```
+## 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`** - a short idenfier for the affected code.  For
+  example `MdePkg`, or `MdeModulePkg/UsbBusDxe`.
+* **`Brief-single-line-summary`** - 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`** - the contributor's signature identifying them
+  by their real/legal name and their email address.
