Check out the Adding a new feature doc to make sure you're trying to add the right type of feature to VA.gov.
vagov-content or Drupal
There are two ways to add a new page to VA.gov; one is by adding it in
vagov-content. The other is to add it to the Drupal CMS. Drupal will eventually be the only source of content, but
vagov-content is expected to be around for the near future.
If you need to add a page to
vagov-content, there is documentation in that repo. You should also contact the website team to coordinate with them on where the new page should live.
If you need to add a page to Drupal, coordinate with the CMS team via your project manager.
