+Building
+
+The coreutils require a POSIX-compliant environment to compile, including a C
+compiler and preprocessor (cc(1) and cpp(1) by default) with the -idirafter
+flag, a Rust compiler (rustc(1) by default), bindgen(1), and a POSIX-compliant
+make(1) utility.
+
+To build and install:
+
+$ make
+$ make PREFIX="/your/preferred/location" install
+
+To build with a different compiler than the default:
+
+$ make CC=clang
+$ make RUSTC=gccrs
+
+To test the utilities:
+
+$ make test
+
+To remove all untracked files:
+
+$ make clean
