Right now configuring SSL requires an administrator to already have certificates, place them in specific directories, and then set up `gitlab.rb` accordingly. We have an opportunity with [Let's Encrypt](https://letsencrypt.org) however to make SSL easier to use out of the box. LE offers a method for requesting widely trusted certificates in an automated way, with security through an online validation process. If it is not, it can print a nice message to inform the user that something is possibly wrong. We will be adding configuration within `gitlab.rb` to provision an LE based SSL certificate for GitLab rails, to address these challenges.
