+# Flipper Zero JavaScript SDK
+This package contains official tooling and typings for developing Flipper Zero
+applications in JavaScript.
+
+## Getting started
+Create your application using the interactive wizard:
+```shell
+npx @flipperdevices/create-fz-app@latest
+```
+
+Then, enter the directory with your application and launch it:
+```shell
+cd my-flip-app
+npm start
+```
+
+You are free to use `pnpm` or `yarn` instead of `npm`.
+
+## Versioning
+For each version of this package, the major and minor components match those of
+the Flipper Zero JS SDK version that that package version targets. This version
+follows semver. For example, apps compiled with SDK version `0.1.0` will be
+compatible with SDK versions `0.1`...`1.0` (not including `1.0`).
+
+Every API has a version history reflected in its JSDoc comment. It is heavily
+recommended to check SDK compatibility using a combination of
+`sdkCompatibilityStatus`, `isSdkCompatible`, `assertSdkCompatibility` depending
+on your use case.
+
+## Documentation
+Check out the [JavaScript section in the Developer Documentation](https://developer.flipper.net/flipperzero/doxygen/js.html)
