 ## XT Toolchain
-This is an the XT toolchain based on MinGW-W64. It currently supports C and C++, and provides
-a variety of tools. It can be used to build both Windows and XT software, including XT OS.
+This is a LLVM/Clang/LLD 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 XT OS. Currently, it is
+targeted at Linux host only, however it should be possible to build it in MSYS2 as well.
 
-This repository contains 2 branches:
- * gnu-toolchain: This is the GCC/Binutils based mingw-w64 toolchain.
- * llvm-toolchain: This is the LLVM/Clang/LLD based mingw-w64 toolchain.
+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:
+ * CMake
+ * LLVM
+ * Make
+ * Mingw-w64
+ * NASM
+ * Ninja
+ * Wine
+
+This software is based on [LLVM MinGW Toolchain](https://github.com/mstorsjo/llvm-mingw).
