+# Customize Paths And Helpers For Devise Routes
+
+Wih a default Devise setup (`devise_for :users`), the sign up/in/out routes are
+located at `/users/sign_up`, `/users/sign_in`, and `/users/sign_out`. And the
+path helpers are `new_user_registration_path`, `new_user_session_path`, and
+`destroy_user_session_path`, respectively.
+
+These can be customized in `config/routes.rb` by opening up the `devise_scope
+:user` block and re-specifying the routes of interest.
+
+```ruby
+Rails.application.routes.draw do
+  devise_for :users
+  devise_scope :user do
+    get 'sign_up', to: 'devise/registrations#new'
+    get 'sign_in', to: 'devise/sessions#new'
+    delete 'sign_out', to: 'devise/sessions#destroy'
+  end
+end
+```
+
+These three custom routes override the paths and helps I described above like
+so:
+
+- `sign_up_path` -> `/sign_up`
+- `sign_in_path` -> `/sign_in`
+- `sign_out_path` -> `/sign_out`
+
+I find these path helpers easier to work with and I like the UX of
+registration/session paths not nested under `/user`.
