+## GMP - Packaged with Dune
+
+More info on GMP: https://gmplib.org/
+
+To use GMP in a _cross-compilation_-friendly way, simply add this library in 
+your library dependencies and make sure it is locally fetched using the 
+`opam-monorepo` plugin (https://github.com/ocamllabs/opam-monorepo).
+
+Example Dune configuration:
+```
+(library my_library)
+ (foreign_stubs (language c) (include_dirs (lib gmp)))
+ (libraries gmp)
+ ...
+)
+```
+
+This configuration enables the inclusion of `gmp.h` and the usage of `gmp` functions, 
+even in a cross-compiled environment such as MirageOS.
