+# Github Pull Request
+
+## **1-Creating a Pull Request**
+
+This guide assumes that you have followed the guide for forking a repository and have made modifications to your local fork that you intend to request be merged
+into the original repository. To start you go to your github repository main page and select the contribute button and then select "Open pull request"
+
+![](../images/images_for_pull_request/CreatePull.png)
+
+This will take you to the pull request form for the main repository which should contain a template for the information that needs to be filled out to create a 
+successful pull request.

+
+The main interface is broken into two main sections
+

+
+The top section is a branch selection dialog that should automatically be filled out properly. On the right is the repository that you are requesting the
+pull request to, as you clicked this from your repository it should be the NIGMS equivalent. Next is the branch of that repository which should be main.
+The next section is the repository you are requesting a pull request from, this should be the repository that you modified and then the branch that your modification 
+is on.
+

+
+The final section is the location where you add a title for your particular request and a description of what changes your pull request has made. A good pull request
+will explain exactly what problem you are solving with your modification, why it should be merged, and what has been changed as an overview. The template for NIGMS 
+repositories also has a checklist that should be completed before a pull request is submitted.
