 # Acb
 
-Welcome to your new gem! In this directory, you'll find the files you need to be able to package up your Ruby library into a gem. Put your Ruby code in the file `lib/acb`. To experiment with that code, run `bin/console` for an interactive prompt.
+Acb is a gem for formatting and outputting csv data from ActiveRecord data
 
-TODO: Delete this and the text above, and describe your gem
-
 ## Installation
 
 Install the gem and add to the application's Gemfile by executing:
 
     $ bundle add acb

-TODO: Write usage instructions here
 
-## Development
+```ruby
+ActiveRecord::Schema.define do
+  create_table :users, force: true do |t|
+    t.string :name
+  end
 
-After checking out the repo, run `bin/setup` to install dependencies. Then, run `rake spec` to run the tests. You can also run `bin/console` for an interactive prompt that will allow you to experiment.
+  create_table :posts, force: true do |t|
+    t.integer :user_id

-To install this gem onto your local machine, run `bundle exec rake install`. To release a new version, update the version number in `version.rb`, and then run `bundle exec rake release`, which will create a git tag for the version, push git commits and the created tag, and push the `.gem` file to [rubygems.org](https://rubygems.org).
