+This is a rough guide on how to build the rust SDK for AppFlowy on android.
 Compiling the sdk is easy it just needs a few tweaks.
 When compiling for android we need the following pre-requisites:
 
-- Android NDK Tools. (v24 has been tested).
+- Android NDK Tools. (v24 has been tested for this) even the latest version works.
 - Cargo NDK. (@latest version).
 
+**Warning** currently the rust backend for android does not compile on windows.

 - Install cargo-ndk ```bash cargo install cargo-ndk```.
-- [Download](https://developer.android.com/ndk/downloads/) Android NDK version 24.
