+* Make this
+
+To make an APK file, you need:
+
+- Android SDK 24.0.3
+
+- OpenJDK (or other Java) JDK (full, not just JRE)
+
+- GNU Make (as on Linux, no installed on macOS or other *BSD)
+
+You maybe need to change some values in Makefile,
+but on Debian no changes needed.
+
+To build, just run ~make~.
+
+If you need to install, connect your Android device
+and run ~make deploy~.
