 ## Session Persistence

 ## Performing OAuth
 ### 1. Add a route to start OAuth
-Add a route to your app to start the OAuth process. In this exmple the `ShopifyAuthController`'s `/login` route.
-The route for starting the OAuth process should use the library's [`ShopifyAPI::Auth::Oauth.begin_auth`](https://github.com/Shopify/shopify-api-ruby/blob/main/lib/shopify_api/auth/oauth.rb#L22) method. 
+Add a route to your app to start the OAuth process.
+
+An example is shown below in a Rails app but these steps could be applied in any framework:
+
+```ruby
+class ShopifyAuthController < ApplicationController
+  def login
+    # This method will trigger the start of the OAuth process
+  end
+end
+```
+
+### 2. Use `Auth::Oauth.begin_auth` method in the route to begin OAuth
+Use the ShopifyAPI library's [`ShopifyAPI::Auth::Oauth.begin_auth`](https://github.com/Shopify/shopify-api-ruby/blob/main/lib/shopify_api/auth/oauth.rb#L22) method to start OAuth process for your app.

 After the app is authenticated with Shopify, the Shopify platform will send a request back to your app using this route (which you provided as a parameter to `begin_auth`, above). Your app will now use the provided `validate_auth_callback` method to finalize the OAuth process. This method returns a hash containing the new session and a cookie to be set in the browser in form of {`session`: `ShopifyAPI::Auth::Session`, `cookie`: `ShopifyAPI::Auth::Oauth::SessionCookie`}.
