Example: https://doc.arvados.org/v2.0/install/crunch2-slurm/install-dispatch.html could be updated to mention the Debian packages first, instead of the "install SLURM from scratch" link:
The Introduction says:
This assumes you already have a SLURM cluster, and have set up all of your compute nodes . For information on installing SLURM, see this install guide.
The "this install guide" string links to https://slurm.schedmd.com/quickstart_admin.html which is a recipe for installation from source.
