 ## Usage
 
+>> Note: Before getting started, ensure that `ENV['HEROKU_API_KEY']` is set. If you do not know your api key, you can `cat ~/.netrc`. Your api key will be listed as password in that file. This is necessary until reading your crendentials out of the `.netrc` file is implemented.
+
 Instantiate Paratrooper with the name of your heroku application
 
 ```ruby
-Paratrooper.new('amazing-app')
+Paratrooper::Deploy.new('amazing-app')
 ```
 
 also you can provide a tag name for repository use
 
 ```ruby
-Paratrooper.new('amazing-app', tag: 'staging')
+Paratrooper::Deploy.new('amazing-app', tag: 'staging')
 ```
 
 Then there are methods available to perform common tasks like creating git tags, running migrations, and warming your application instance.
