 # toolchain
-The toolchain that is used to build yiffOS
+The toolchain that is used to build yiffOS.
+
+You'll need a working clang + gcc setup on the host system to run these scripts.
+
+You'll also need the sources for:
+	binutils 2.36.1
+	gcc 10.2.0
+	linux 5.13.13
+	glibc 2.33
+	openssl 1.1.1l
+	cmake 3.21.1
+	llvm 12.0.1
+
+To allow the scripts to find the sources, please ensure the extracted sources are in a folder with only it's name as the folder name. (Example: gcc 10.2.0 would be in /sources/gcc)
+
+A destination folder and a target folder will need to be created to allow the toolchain to properly link.
+
+Script Usage:
+./create-toolchain.sh "destination folder" "target folder" "source folder" "makeflags"
