-2. Add `https://webdlanding.wizardsoftware.net` as an allowed home url
-3. Restart FileMaker Services
-4. Add postMessage forwarding script as referenced in https://github.com/WizardSoftware/WebDLanding/issues/6

+
+### Add `https://webdlanding.wizardsoftware.net` as an allowed home url
+
+Update the `jwpc_prefs.xml` file located in the `/Web Publishing/conf/jwpc_prefs.xml`
+
+```xml
+<parameter name="customhomeurl">https://webdlanding.wizardsoftware.net</parameter>
+```
+
+### Restart FileMaker Services
+
+🪟➕R => services.msc => FileMaker Server => Restart
+
+### Add postMessage forwarding script as referenced in https://github.com/WizardSoftware/WebDLanding/issues/6
+
+Add the following snipet as a file named `message-forward.js` to FMServer Root Site `/HTTPServer/conf`:
+
+```js
+window.addEventListener("message", d => {
+    // find all frames inside the webdirect session
+    let frames = Array.from(document.getElementsByTagName("iframe"));
+    if (frames.length) {
+        // fore each frame found, relay the event by re-posting it down to the child frame
+        frames.forEach(frame => {
+            frame.contentWindow.postMessage(d.data, "*")
+        });
+    }
+});
+```
+
+#### Web.Config Mods
+
+Rewrite Section
+
+Add two new Outbound Rules
+
+```xml
+<rule name="RestoreAcceptEncoding" preCondition="NeedsRestoringAcceptEncoding">
+<match serverVariable="HTTP_ACCEPT_ENCODING" pattern="^(.*)" />
+  <action type="Rewrite" value="{HTTP_X_ORIGINAL_ACCEPT_ENCODING}" />
+</rule>
+<rule name="AddPostMessageForwarding" preCondition="IsHTML" patternSyntax="ExactMatch">
+  <match filterByTags="None" pattern="&lt;/body>" />
+  <action type="Rewrite" value="&lt;script type='text/javascript' src='/message-forward.js'>&lt;/script>&lt;/body>" />
+</rule>
+```
+
+Add two PreConditions
+
+```xml
+<preConditions>
+  <preCondition name="IsHTML">
+    <add input="{RESPONSE_CONTENT_TYPE}" pattern="^text/html" />
+  </preCondition>
+  <preCondition name="NeedsRestoringAcceptEncoding">
+    <add input="{HTTP_X_ORIGINAL_ACCEPT_ENCODING}" pattern=".+" />
+  </preCondition>
+</preConditions>
+```
+
+Update the existing inbound rule: `FMWebPublishing` adding two http server variables:
+
+```xml
+<set name="HTTP_X_ORIGINAL_ACCEPT_ENCODING" value="{HTTP_ACCEPT_ENCODING}" />
+<set name="HTTP_ACCEPT_ENCODING" value="" />
+```
+
+Add both of the above variables to the allowed variables list:
+
+```xml
+<allowedServerVariables>
+  <add name="HTTP_SEC_WEBSOCKET_EXTENSIONS" />
+  <add name="HTTP_X_ORIGINAL_ACCEPT_ENCODING" />
+  <add name="HTTP_ACCEPT_ENCODING" />
+</allowedServerVariables>
+```
