+# How to use?
+
+# If you have Nix installed, you can get in an environment with everything
+# needed to compile Coq and CoqIDE by running:
+# $ nix-shell
+# at the root of the Coq repository.
+
+# How to tweak default arguments?
+
+# nix-shell supports the --arg option (see Nix doc) that allows you for
+# instance to do this:
+# $ nix-shell --arg ocamlPackages "(import <nixpkgs> {}).ocaml-ng.ocamlPackages_4_05" --arg buildIde false
+
+# You can also compile Coq and "install" it by running:
+# $ make clean # (only needed if you have left-over compilation files)
+# $ nix-build
+# at the root of the Coq repository.
+# nix-build also supports the --arg option, so you will be able to do:
+# $ nix-build --arg doInstallCheck false
+# if you want to speed up things by not running the test-suite.
+# Once the build is finished, you will find, in the current directory,
+# a symlink to where Coq was installed.
