+# Some notes about unicorn
+
+First off, it only servers the rails application, not the static assets.
+You need to have another webserver for this.
+
+## SECRET_KEY
+
+By default rails reads the secret key from the environment variable
+`SECRET_KEY_BASE`. It is possible to create a key with `rake secret`
+
