 * github-api plugin (https://wiki.jenkins-ci.org/display/JENKINS/GitHub+API+Plugin)

         * Jenkins will create a token credential, and give you the id of the newly created credentials.  The default description is: `serverAPIUrl + " GitHub auto generated token credentials"`.
     * For username/password use `Kind` -> `Username with password`
       * The scope determines what has access to the credentials you are about to create
+    * For Github App use `Kind` -> `Github App`
+      * For App ID use the App ID associated with the Github App you've created
+      * For secret, copy and paste the contents of the pem file you generated from your Github App
+      * Option to select `Advanced` and add an Owner
     * The first part of the description is used to show different credentials in the drop down, so use something semi-descriptive
     * Click `Add`
   * Credentials will automatically be created in the domain given by the `GitHub Server API URL` field.
