To get your app running on AppSignal you start by clicking the "add app" link on the application overview page.
You will see instructions on how to install AppSignal in your app.
The first step is to add the AppSignal gem to your bundle. You then run a generator that will create a config file with the correct API key. There are various ways to inform AppSignal about deploys of your app with Capistrano and Heroku amongst others.
The installation instructions contain all the information needed to set up including easily copy-pastable commands that contain the correct information for your specific app.
Once you deploy AppSignal will start receiving data and you're good to go!
