+    * Steps to Create Branch: 
+        1. Checkout the master
+            * $ git checkout master
+        2. Make sure your local copy of the master branch is up to date
+            * $ git pull
+        3. Create the branch:
+            * $ git branch {BRANCH_NAME}
+        4. Switch to the new branch
+            * $ git checkout {BRANCH_NAME}
+        5. Make any desired first commit changes
+        6. Commit branch
+            * $ git commit -m "	Creating new branch {BRANCH_NAME} and updating documents"
+        7. Push Branch
+            * $ git push --set-upstream origin {BRANCH_NAME}
 2. Push all your changes into the Branch
     * For Pull Requests from External Contributors, those changes will also go into the Release Branch and not the Master
 3. Create a Pull Request to merge the changes from the Branch into Master
