+
+## Running the App
+
+1. Open `index.html` in your web browser.
+
+## Project Structure
+
+- `index.html`: Main HTML file that sets up the structure of the web page.
+- `assets/script.js`: JavaScript file that handles the LENS authentication and popup window.
+- `assets/style.css`: CSS file for styling the web page.
+- `.gitignore`: Specifies files and directories to be ignored by Git.
+
+## Usage
+
+### Popup Window
+
+- The `index.html` file includes a script that opens a popup window to `https://lens.admin-host.com` and listens for messages from this origin.
+- When a message is received from the popup, it is logged to the console and displayed on the page.
+
+## Notes
+
+- Ensure that the domain you are using is registered with LENS. For testing purposes, you can register `localhost`.
+- The browser logs the status and received data to the console.
