+> Snakemake version 8 introduces breaking changes with respect to the Snakemake cookiecutter profile. One new
+> feature is that execution of jobs on a cluster or the cloud are handled by
+> [executor plugins](https://snakemake.readthedocs.io/en/stable/tutorial/additional_features.html#cluster-or-cloud-execution).
+> For instance, there is a
+> [dedicated executor plugin for SLURM](https://snakemake.github.io/snakemake-plugin-catalog/plugins/executor/slurm.html) that
+> provides much of the functionality that was previously catered for by this snakemake profile. Profiles are still needed, but their
+> role changes somewhat to that of fine-tuning executor plugins for particular sites, only requiring the yaml configuration
+> file.
+>
+> With this in mind, support for Snakemake version 8 has currently been put on hold and I recommend that users consult
+> the executor plugin documentation for slurm.
