Environ requires a Quantum ESPRESSO installation. At the very simplest, one can install the pw.x program by cloning quantum-espresso here and checking out the tag qe-6.4 for the most up to date version. Alternatively one can download the archive at the release page. Then,

1. Configure QE following the standard procedure.
2. Compile QE without the Environ module.
3. Extract the Environ module into desired directory (we typically assume the Environ module resides in the QE root directory.
4. Run the QE script addsonpatch.sh with the -patch option (this script is in the QE install folder and requires 3 additional arguments, the module name, the location of the files to compile, e.g. Environ/src, and the location to place links, e.g. Modules).
5. Run the Environ script environpatch.sh (located in the Environ/patches folder) with the -patch option.
6. Run the QE script to regenerate modules' dependencies (located in the QE install directory).
7. Recompile QE
