These environments are created in ``sunbeam/.snakemake/`` by default.
 
-The accompanying files named something like ``ENV_NAME.ARCH.pin.txt`` are generated with ``snakedeploy``. They list all the packages and exact versions in a given environment (for the architecture they were generated on, e.g. linux-64) so that snakemake can first try to use that exact environment and only if it fails, try to solve the ``.yml`` file for itself.
