+add new cli command to setup proxy for developing and debugging custom ui locally
+
+This command will establish a proxy tunnel between the following 3 entities together: your Logto cloud auth services, your application, and your custom sign-in UI.
+
+Assuming you have a custom sign-in page running on `http://localhost:4000`.
+Then you can execute the command this way:
+
+```bash
+npm cli proxy --endpoint https://<tenant-id>.logto.app --port 9000 --experience-uri http://localhost:4000
+```
+
+Or if you don't have your custom UI pages hosted on a dev server, you can use the `--experience-path` option to specify the path to your static files:
+
+```bash
+npm cli proxy --endpoint https://<tenant-id>.logto.app --port 9000 --experience-path /path/to/your/custom/ui
+```
+
+This sets up the proxy and it will be running on your local machine at `http://localhost:9000/`.
+
+Finally, run your application and set its Logto endpoint to the proxy address `http://localhost:9000/` instead.
+
+If all set up correctly, when you click the "sign-in" button in your application, you should be navigated to your custom sign-in page instead of Logto's built-in UI, along with valid session (cookies) that allows you to further interact with Logto experience API.
+
+Happy coding!
