CNA Processes Documentation Now on GitHub

We have updated the collection of processes documentation for CVE Numbering Authorities (CNAs) on our CVEProject Documentation website on GitHub.

The purpose of the collection is to provide training and assistance to CNAs so that they can correctly fulfill their responsibilities for properly writing and completing the information required for each CVE Entry they submit to the Primary CNA to be added to the CVE List, as defined by the CNA Rules, Version 2.0.
