+# Firebase support
+
+## Pascal API
+This directory contains the firebase messaging support files for Pas2JS.
+The src directory contains the firebaseapp unit which provides an interface
+for Firebase Cloud messaging APIs from Google.
+
+## Support files
+The js directory contains the support files needed to make it work.
+The Google API compatibility API is used, the version saved in the js
+directory is known to work.
+
+You must use these files in your main HTML file:
+```html
+
+
+```
+
+The firebase-messaging-sw.js file is a small service worker file that you can register
+with the following call :
+```javascript
+Window.Navigator.serviceWorker.register('firebase-messaging-sw.js')
+```
+
+A demo application can be found in FPC fcl-web/examples/fcm/webclient
+
