 Configuration
 -------------
 
-This application depends on at least those two Twitter-related tokens:
-
-- `RT_CONSUMER_KEY`
-- `RT_CONSUMER_SECRET`
-
-Make sure to set them before using.
-
-Optionally, setting those two variables allows you access to private accounts which your account has access to:
-
-- `RT_ACCESS_TOKEN`
-- `RT_ACCESS_TOKEN_SECRET`
-
-It is also recommended to have memcached installed so tweet requests will be cached
-for a short while.
-
-- `RT_MEMCACHED_SERVERS` (separate multiple servers with comma)
-
-Alternatively, create a config file. Read `config/config_init.rb` for hints.
