+2. Create application
+
+  heroku create --stack cedar my-peergroup-app-name
 
-   bundle exec compass compile -e production --force
+3. Setup configuration variables
 
-On production server mysql database is used.
+  heroku config:add NODE_PORT=80 NODE_USERNAME=node NODE_PASSWORD=secret NODE_PROTOCOL=http
 
-Credentials are stored in non tracked file config/database.yml
+* NODE_USERNAME/NODE_PASSWORD - credentials that will allow node server to connect

+4. Add redis addon
 
-If you don't have mysql database at all, you can bundle gems by: bundle install --without production
+  heroku addons:add redistogo:nano
 
-Node server is managed by init script placed in /etc/init.d/node-peergroup
+5. Deploy code
 
-Deployment is done by Capistrano.
+  git push heroku master
 
-Deployment process:
+Refer to heroku [docs](http://devcenter.heroku.com/articles/rails31_heroku_cedar) for more informations.
 
-* make changes, commit and push to github server
-* from your local machine, type: cap deploy
