 ## Developer Access
 
 Currently the core team consists of @joshuaboniface, @nvllsum, @JustAMan, @dcrdev, and @anthonylavado. One of the core team members is required to merge code. We may augment this team in the future at our discretion, but for now we seek to keep this team a small group while we establish ourselves.
