 You get the Telegram API ID and hash as soon as you've registered your own application on [https://my.telegram.org](https://my.telegram.org).
 
-Moreover, you need to have a compiled version of [TDLib 1.8.3](https://github.com/tdlib/td) or higher in the sub-directory `tdlib`. This sub-directory must contain another sub-directory that fits to the target device architecture (e.g. armv7hl, i486). Within this directory, there needs to be a folder called `lib` that contains at least `libtdjson.so`. For armv7hl the relative path would consequently be `tdlib/armv7hl/lib`.

 You may just want to download the [tdlib.zip from our fork](https://github.com/Wunderfitz/td/releases) to just use the exact version of the latest official Fernschreiber release. To use it, you need to extract it into your local `tdlib/` folder as described above. If so, you're done and can compile Fernschreiber using the Sailfish SDK. If you want to build TDLib for yourself, please keep on reading.
