To release a new version, update the version number in `version.rb`, and then run `bundle exec rake release`, which will create a git tag for the version, push git commits and tags, and push the `.gem` file to [rubygems.org](https://rubygems.org).

+If you were to set up a meroku clone for your personal use, you would need
+
+  - A secret ( a 12 charactor hex string )
+  - An s3 bucket with the name $secret
+  - Your Ec2 default security group should allow all traffic
+  - An elastic ip allocation. Usually has a name like "eipalloc-..."
+  - A free certificate for your domain from letsencrypt
+  - You would also need a wildcard certificate so that consumer apps work without warnings in https:// mode
