I just saw someone link to this page as an authoritative source. Is it just me or it needs some serious rework? https://github.com/tootsuite/documentation/blob/master/Running-Mastodon/Resources-needed.md

It was last updated in July 2017. Listing % of CPU and RAM used seems pointless, as if you are not utilizing close to 100% of what you have, then you are wasting money / could configure Mastodon to use more. Sidekiq threads and DB_POOL should be the same number, always. Disk usage seems like an odd metric, it's user-uploaded data.
