You can add readers and writers to a class using one of the 3 commands

```ruby
class Item
  attr_reader :name
  def initialize(name)
    @name = name
  end
end

item1 = Item.new("Clock")
item1.name
```
Will turn "Clock"

```ruby
class Item
  attr_writer :name
  def initialize(name)
    @name = name
  end
end

item1 = Item.new("Clock")
item1.name = "Bike"
p item1.name
```

Will return "Bike"

attr_accessor does both attr_reader and attr_writer at the same time.
