-# Rails Serializers
-
-What are Serializers? Well Rails API's returns JSON data in full, so serializers allows us to cherry pick the exact data we want in a much organized fashion. Instead of getting every column from the returned data, we can grab which ever we allow to pass through.
-
-| Normal Model        | Serializer Model    | 
-| ------------- |:-------------:|
-| id, name, rating, director, score, actors_id, created_at, updated_at| id, name, rating|
-
-We are able to tell the Rails API what to fetch rather than the frontend; making it much more simple and faster to scaffold your next project.
-
-1. Installation
-
-Open your ```gemfile``` and add the serializer gem into your project 
-```ruby
-# Serializer
-gem 'active_model_serializers'
-```
