It is easy to use a third-party repository with Guix. Just export the
variable GUIX_PACKAGE_PATH to point to the repository as described here:

https://www.gnu.org/software/guix/manual/guix.html#Package-Modules

See e.g. these repositories for examples:

https://github.com/BIMSBbioinfo/guix-bimsb
https://github.com/MRC-CLIMB/guix-climb

Hope this helps!
