 In theory, you're not setting up with vagrant, either, and shouldn't need a vagrant user; however, again, all the seed data assumes 'vagrant'. To avoid headaches, it's probably best to go with this flow, so again, we create a 'vagrant' user.

 ## Setting up your Discourse
 
 ###  Check out the repository
-
-    git@github.com:discourse/discourse.git ~/discourse
-    cd ~/discourse # Navigate into the repository, and stay there for the rest of this how-to
-
+```sh
+git clone git@github.com:discourse/discourse.git
+cd discourse # Navigate into the repository, and stay there for the rest of this how-to
+```
 ### What about the config files?
 
 If you've stuck to all the defaults above, the default `discourse.conf` and `redis.conf` should work out of the box.
 
 ### Install the needed gems
-
-    bundle install # Yes, this DOES take a while. No, it's not really cloning all of rubygems :-)
+```sh
+bundle install
+```
 
 ### Prepare your database
-
-    rake db:migrate
-    rake db:test:prepare
-    rake db:seed_fu
+```sh
+rake db:create
+rake db:migrate
+rake db:test:prepare
+rake db:seed_fu
+```
 
 ## Now, test it out!
-
-    bundle exec rspec
-
+```sh
+bundle exec rspec
+```
 All specs should pass
 
 ### Deal with any problems which arise.
