+# Momentum FW JavaScript SDK
+This package contains tooling and typings for developing Flipper Zero
+applications in JavaScript for Momentum Custom Firmware.
+
+This is a fork of the [Official Flipper Zero JS SDK](https://www.npmjs.com/package/@flipperdevices/fz-sdk),
+with added types for the extra features provided by the Momentum JavaScript API.
+
+Scripts made for Official Flipper Zero JS SDK will work on Momentum Firmware too.
+If you use extra features provided by Momentum, you are encouraged to use syntax like
+`if (doesSdkSupport(["feature-name"])) { ... }` so that your JS app can work on Official
+Firmware too, aswell as all other compliant Custom Firmwares. If some of those extra
+features are essential to the functionality of your app, you can use `checkSdkFeatures(["feature1", "feature2"])`
+near the beginning of your script, which will show a warning to the user that these features
+are not available in their firmware distribution.
