## Installation procedure for Guix users
QMCkl can be installed with the [GNU Guix](https://guix.gnu.org) functional package manager.
The [qmckl.scm](https://github.com/TREX-CoE/qmckl/blob/master/tools/qmckl.scm)
Schema file contains the manifest specification for the `qmckl` installations.
It can be installed within the selected `$GUIX_PROFILE` as follows:
```
guix package \
--profile=$GUIX_PROFILE \
--load-path=<path_to_trexio_scm> \
--cores=<n_cores> \
--install-from-file=qmckl.scm
```
where `<path_to_trexio_scm>` should point to a folder, which contains the TREXIO manifest file
[trexio.scm](https://github.com/TREX-CoE/trexio/blob/master/tools/trexio.scm)
(e.g. `~/trexio/tools/` if TREXIO repository was cloned under $HOME).
Installation procedures for both development version (`qmckl-dev`)
and stable releases (`qmckl-hpc`) are provided.
One can switch between them using the return value (last line)
in the `qmckl.scm` file.
