+## Build the Content
+You can run ``make`` in the top-level directory to build OpenControl content for all subprojects. Alternatively, you can ``cd`` into a project directory and run things one at a time.

+For example, to build OpenShift v3 content:
+`````
+$ cd OpenShift-v3
+$ make
+`````
+Inside the ``exports`` directory, you will now see two files:
+  * ``FedRAMP-Filled-v2.1.docx``: Completed FedRAMP template with your security controls
+  * ``OpenShift_v3_Compliance.pdf``: DocBook style, breakouts controls without formatting
