3. bundle install --deployment to get the necessary gems
4. Copy config/template_newrelic_plugin.yml to config/newrelic_plugin.yml
5. Edit config/newrelic_plugin.yml and replace "YOUR_LICENSE_KEY_HERE" with your New Relic license key
6. Edit config/newrelic_plugin.yml and add the full path to your passenger-status and passenger-memory-stats command as well as the version used. Make sure you determine the right version and paths, many systems have several passenger gems/packages installed.
