 Teudu
----
+===
 
 This is the teudu webservice. It's based off of RoR 3.1.
+
+Deploying
+---
+
+I don't know if we're ready for that yet...
+You can push back to here by typing: `git push`
+
+And to Heroku with: `git push heroku master`
+
+Database
+---
+
+We test online with the app deployed to Heroku. Since Heroku uses Postgres instead of sqlite, you should run bundle install with the development context.
+`bundle install --without production`
