+# Overview steps
+
+Integrating SuperTokens with a Next.js app involves:
+- Calling the frontend and backend init functions
+- Adding a website page to display the auth related widgets (on `/auth` by default)
+- Creating a serverless function to expose the auth related APIs which will be consumed by the frontend widgets (on `/api/auth/` by default)
+- Protecting website routes: Displaying them only when a user is logged in, else redirecting them to the login page
+- Performing session verification:
+    - In your APIs
+    - In your frontend routes
+
+## Try an example app
+Download and run an example NextJS app quickly using the following command:
+
+```bash
+npx create-supertokens-app@latest --frontend=next --recipe=^{codeImportRecipeName}
+```
