 ## Building the android version
-* Due to a [bug](https://bugreports.qt.io/browse/QTBUG-113851) in the Qt/cmake/gradle build system for android, you need to delete all `libc.so` files from the build dir before rebuilding (yes! no, that's not a joke). There is a script that does that in linux [renderer/android/workaround_qt_cmake_build_bug.sh](https://github.com/AlpineMapsOrg/renderer/blob/main/android/workaround_qt_cmake_build_bug.sh), please don't run it anywhere important, definitely not as root;) ). You can add it as a custom build step before everything else in qt creator (in the %{buildDir} working directory).
+* We are usually building with Qt Creator, because it works relatively out of the box. However, it should also work on the command line or other IDEs if you set it up correctly.
+* You need a Java JDK before you can do anything else. Not all Java versions work, and the error messages might be surprising (or non-existant). I'm running with Java 19, and I can compile for old devices. Iirc a newer version of Java caused issues. [Android documents the required Java version](https://developer.android.com/build/jdks), but as said, for me Java 19 works as well. It might change in the future.
+* Once you have Java, go to Qt Creator Preferences -> Devices -> Android. There click "Set Up SDK" to automatically download and install an Android SDK.
+* Finally, you might need to click on SDK Manager to install a fitting SDK Platform (take the newest, it also works for older devices), and ndk (newest as well).
+* Then Google the internet to find out how to enable the developer mode on Android.
+* On linux, you'll have to setup some udev rules. Run `Android/SDK/platform-tools/adb devices` and you should get instructions.
+* If there are problems, check out the [documentation from Qt](https://doc.qt.io/qt-6/android-getting-started.html) 
+* Finally, you are welcome to ask in discord if something is not working! 
 
 ## Building the WebAssembly version:
 * Atm, none of the Qt versions works perfectly in all browsers
 * In Qt 6.6 touch doesn't work on Firefox (issues #33)
-* [WebAssembly version compatible with the Qt version](https://doc-snapshots.qt.io/qt6-dev/wasm.html#installing-emscripten)
-* The threaded version doesn't seem to work atm, so use the non-threaded!
+* [The Qt documentation is quite good on how to get it to run](https://doc-snapshots.qt.io/qt6-dev/wasm.html#installing-emscripten). Be aware that only specific versions of emscripten work for specific versions of Qt, and the error messages are not helpfull.
+* The threaded version doesn't seem to work atm, so use the non-threaded (bug reported)!
 * There are a number of other bugs, we track them with the upstream tag.
