Add a profile controller

  include Gatleon::Rails::Authform::Concern.new(public_key: AUTHFORM_FORM_PUBLIC_KEY, secret_key: AUTHFORM_FORM_SECRET_KEY)

  before_action :require_login, only: [:index]

  def index
    erb = <<~ERB
      <h1>Profile</h1>
      <p style="color: green;">You are signed in.</p>
      <p><%= current_user %></p>
    ERB

    render inline: erb
  end

  def signin
    erb = <<~ERB
      <p style="color: red;"><%= flash[:error] %></p>
      <h1>Sign In</h1>
      <form action="https://authform.gatleon.com/v1/form/<%= ProfileController::AUTHFORM_FORM_PUBLIC_KEY %>" method="POST">
        <input type="email" name="email">
        <button type="submit">Sign In</button>
      </form>
    ERB

    render inline: erb
  end

  private

  def require_login
    unless current_user
      flash[:error] = "Sign in, please."

      redirect_to(profile_signin_path) and return
    end
  end
end
```

Add profile routes to routes.rb

Rails.application.routes.draw do
  get '/profile', to: 'profile#index', as: 'profile'
  get '/profile/signin', to: 'profile#signin', as: 'profile_signin'
end
