 # WebDLanding
 
-Web-Direct landing page to suppress annoyances and route users to the appropriate solution.
+Web-Direct Landing page for Wizard Web-Direct deployed solutions.
+
+## Features
+
+- `onbeforeunload` support.
+
+Best effort to warn users that refreshing the page, or otherwise navigating away will lose their place in the system. Support varies by browser.
+
+- Back button suppression / integration.
+
+Avoid back button taking the user out of the solution, and provide support for solutions to listen to the native browser back button and react accordingly.
+
+## Back Button Integration
+
+WebDLanding provides an opportunity for back button support to be added, by posting a message to child iframes that the back button was pressed.
+
+A sample of the web viewer content that must be provided on each layout:
+
+```html
+<!DOCTYPE html>
+<html lang="en">
+
+<head>
+    <meta charset="utf-8" />
+    <meta name="viewport" content="width=device-width, initial-scale=1.0, maximum-scale=1" />
+</head>
+
+<body></body>
+
+<script>
+    window.addEventListener("message", (d) => {
+        if (d.data === "BackButtonPressed") {
+            FileMaker.PerformScript("back_button", "");
+        }
+    });
+</script>
+
+</html>
+```
