```ruby
class GoogleClientSettings

  attr_reader client_id, client_secret, user_email

  def initialize(client_id, client_secret, user_email)
    @client_id = client_id
    @client_secret = client_secret
    @user_email = user_email
  end

end```

Change attribute to have symbolic name
user
```ruby
class GoogleClientSettings

  attr_reader :client_id, :client_secret, :user_email

  def initialize(client_id, client_secret, user_email)
    @client_id = client_id
    @client_secret = client_secret
    @user_email = user_email
  end

end```
