A simple Sinatra template modeled after Flask Heroku.

Once you've cloned the repo, simply run:

bundle install

To start up the development server, run the following:

bundle exec thin start

If, however, you would prefer to create a screen process to run the development server, then you could use the following commands:

screen -S server
cd path/to/sinatra/template
bundle exec thin start

You can then detach the screen process with CTRL-A-D. To reattach the process, simply run:

screen -R server

To upload your application to Heroku, make sure you first have the Heroku gem installed. Then run the following command (with the name of your application substituted for app_name):

heroku create app_name --stack cedar
git push heroku master

Attaching your own custom domain to your Heroku instance is pretty easy.

heroku addons:add custom_domains
heroku domains:add example.com
heroku domains:add www.example.com

Make sure to attach the following A records using your DNS management tool:

75.101.163.44
75.101.145.87
174.129.212.2
