 ## XT Toolchain
-This is a GNU-based mingw-w64 toolchain. It currently supports C and C++, and provides a variety of
-tools including IDL, message and resource compilers. The XT Toolchain is also the official build
-environment for compiling XT software, including the FerretOS. Currently, it is targeted at Linux
-host only, however it should be possible to build it in MSYS2 as well.

+targeted at Linux host only, however it should be possible to build it in MSYS2 as well.
+
+Benefits of a LLVM based MinGW toolchain are:
+ * Single toolchain targeting all architectures (i686, x86_64, armv7 and aarch64),
+ * Support for generating debug info in PDB format,
+ * Support for targeting ARM/AARCH64 architectures and ability to produce Windows ARM binaries.

 This software includes:
- * Binutils
 * CMake
- * GCC
+ * GNU Assembler
+ * LLVM
 * Make
 * Mingw-w64
 * Ninja
 * Wine

+This software is based on [LLVM MinGW Toolchain](https://github.com/mstorsjo/llvm-mingw).
