+OpenFOAM.org
+============
+
+Para compilar e instalar este proyecto en el store:
+
+```
+nix-build
+```
+
+Para cargarlo en el entorno:
+
+```
+nix-env -i ./result
+```
+
+El entorno deja creados wrappers a todos los ejecutables de OpenFOAM.
+Los wrappers se encargan de importar el `bashrc` previo a ejecutar los comandos.
+Puede importarse el `bashrc` con:
+
+```
+source result/lib/OpenFOAM-20220727/etc/bashrc
+```
+
+y eso anulará los wrappers.
