-Require these files in your Rakefile so that you can run `rake qc:work`.

-```ruby
-require "queue_classic"
-require "queue_classic/tasks"

 By default, queue_classic will use the QC_DATABASE_URL falling back on DATABASE_URL. The URL must be in the following format: `postgres://username:password@localhost/database_name`.  If you use Heroku's PostgreSQL service, this will already be set. If you don't want to set this variable, you can set the connection in an initializer. **QueueClassic will maintain its own connection to the database.** This may double the number of connections to your database. Set QC::Conn.connection to share the connection between Rails & QueueClassic
 
 ```ruby
 require 'queue_classic'
 QC::Conn.connection = ActiveRecord::Base.connection.raw_connection
 ```
 
-**Note on using ActiveRecord migrations:** If you use the migration, and you wish to use commands that reset the database from the stored schema (e.g. `rake db:reset`), your application must be configured with `config.active_record.schema_format = :sql` in `config/application.rb`.  If you don't do this, the PL/pgSQL function that queue_classic creates will be lost when you reset the database.
+Next you need to run the queue classic generator to create the database
+migration. This will setup the necessary table to use queue classic.
 
-```ruby
-require 'queue_classic'
-
-class AddQueueClassic < ActiveRecord::Migration
-  def self.up
-    QC::Setup.create
-  end

-  def self.down
-    QC::Setup.drop
-  end
