+# ActiveRecord::Mysql::Enum
+
+This gem is an extension to ActiveRecord which enables native support of
+enumerations in the database schema using the ENUM type in MySQL. Forked
+and revitalized from [enum_column3](https://github.com/jewlr/enum_column)
+which was itself a fork of a fork of Nick Pohodnya's original gem for
+Rails 3, [enum_column3](https://github.com/electronick/enum_column).
+
+## Support
+Currently this has been manually tested with Rails version 4 and 5, and works with scaffolding.
+
+**Supported adapters:**
+- mysql
+- mysql2
+- jdbcmysql (by Nilesh Trivedi)
+
+## Installation
+In your `Gemfile` add the following snippet
+```ruby
+gem 'activerecord-mysql-enum', '~> 0.1', require: 'active_support/mysql/enum'
+```
+
+## Usage
+### Schema Definitions
+When defining an enum in your schema, specify the constraint as a limit:
+```ruby
+create_table :enumerations, :force => true do |t|
+  t.column :severity, :enum, :limit => [:low, :medium, :high, :critical], :default => :medium
+  t.column :color, :enum, :limit => [:red, :blue, :green, :yellow]
+end
+```
+
+### Model Validations
+You can then automatically validate this column using:
+```ruby
+validates_columns :severity, :color
+```
+
+### Setting/Getting Values
+All enumerated values will be given as symbols.
+```ruby
+@e = Enumeration.new
+@e.severity = :medium
+```
+
+You can always use the column reflection to get the list of possible values from the database column.
+```ruby
+irb(1)> Enumeration.columns_hash['color'].limit
+=> [:red, :blue, :green, :yellow]
+irb(2)> @enumeration.column_for_attribute(:color).limit
+=> [:red, :blue, :green, :yellow]
+```
+
+### Form Helpers
+You can use enum_select helper to generate input for enumerated attribute as:
+```ruby
+<%= enum_select(@enumeration, 'severity')%>
+```
+
+Or using `form_for`:
+```ruby
+<%= form_for @enumeration do |f| %>
+  <%= f.label :severity %>
+  <%= f.enum_select :severity %>
+<% end %>
+```

-Overview
-
-  This gem is an extension to ActiveRecord which enables native support of enumerations in the database schema using the ENUM type in MySQL.
-  Currently only MySQL is implemented.
-  Tested with Rails 3, for Rails 2 you should better use enum-column plugin (http://rubyforge.org/projects/enum-column/)
-  Works with Scaffolding.
-
-  Supported adapters:
-    mysql
-    mysql2
-    jdbcmysql (by Nilesh Trivedi)
-
-How to use it.
-
-In you Gemfile:
-
-  gem 'enum_column3'
-
-In your schema:
-
-  When you create your schema, specify the constraint as a limit:
-
-    create_table :enumerations, :force => true do |t|
-      t.column :severity, :enum, :limit => [:low, :medium, :high, :critical], :default => :medium
-      t.column :color, :enum, :limit => [:red, :blue, :green, :yellow]
-      ...
-    end
-
-
-In the model:
-
-  You can then automatically validate this column using:
-
-    validates_columns :severity, :color
-
-  The rest will be handled for you. All enumerated values will be given as symbols.
-
-    @e = Enumeration.new
-    @e.severity = :medium
-
-You can always use the column reflection to get the list of possible values from the database column.
-
-    Enumeration.columns_hash['color'].limit
-    or
-    @enumeration.column_for_attribute(:color).limit
-    
-    Will yield: [:red, :blue, :green, :yellow]
-   
-
-In views:
-
-  You can use enum_select helper to generate input for enumerated attribute as:
-
-     <%= enum_select(@enumeration, 'severity')%>
-     or
-     <%= form_for @enumeration do |f| %>
-        <%= f.label :severity %>
-        <%= f.enum_select :severity %>
-     <% end %>
