+# Coq {#sec-language-coq}
+
+Coq libraries should be installed in `$(out)/lib/coq/${coq.coq-version}/user-contrib/`. Such directories are automatically added to the `$COQPATH` environment variable by the hook defined in the Coq derivation.
+
+Some extensions (plugins) might require OCaml and sometimes other OCaml packages. The `coq.ocamlPackages` attribute can be used to depend on the same package set Coq was built against.
+
+Coq libraries may be compatible with some specific versions of Coq only. The `compatibleCoqVersions` attribute is used to precisely select those versions of Coq that are compatible with this derivation.
+
+Here is a simple package example. It is a pure Coq library, thus it depends on Coq. It builds on the Mathematical Components library, thus it also takes `mathcomp` as `buildInputs`. Its `Makefile` has been generated using `coq_makefile` so we only have to set the `$COQLIB` variable at install time.

+```nix
+{ stdenv, fetchFromGitHub, coq, mathcomp }:

+stdenv.mkDerivation rec {
