 # Introduction
 DroidFS relies on modified versions of the original encrypted filesystems programs to open volumes. [CryFS](https://github.com/cryfs/cryfs) is written in C++ while [gocryptfs](https://github.com/rfjakob/gocryptfs) is written in [Go](https://golang.org). Thus, building DroidFS requires the compilation of native code. However, for the sake of simplicity, the application has been designed in a modular way: you can build a version of DroidFS that supports both Gocryptfs and CryFS, or only one of the two.
 
-Moreover, DroidFS aims to be accessible to as many people as possible. If you encounter any problems or need help with the build, feel free to open an issue, a discussion, or contact me by [email](mailto:hardcore.sushi@disroot.org) or on [Matrix](https://matrix.org): @hardcoresushi:matrix.underworld.fr

 # Setup

+The following two steps assume you're using a Debian-based Linux distribution. Package names might be similar for other distributions. Don't hesitate to ask if you're having trouble with this.

If you succeed in building it with a more recent version of NDK, please report it.
