 **cryptoGX** is a java based software for en- / decrypting texts or files and secure delete files.
 It was designed to be controlled with a GUI, but can also be used from the command line.
 
-Because the GUI uses javaFX, java version from 1.8.0_40 to 10.* with javaFX support is required.
-Alternatively you can compile the [source code](#https://github.com/blueShard-dev/cryptoGX/archive/master.zip) with higher
-java version and include [javaFX](#https://openjfx.io/) manually
+Because the GUI uses javaFX, java version from 1.8.0_40 to 10.* with javaFX support is required (also applies to windows .exe files).
