I’d encourage you to follow the Ansible install instructions for admins. I’m a bit more technically inclined than my peers, but by no means a pro. The Ansible instructions were super simple to get going with a Digital Ocean droplet, although you can really run Lemmy on any piece of hardware you have SSH access to. (The benefit of digital ocean or any other cloud provider is you can scale up resources quickly)
I am happy to help guide you and other new would-be admins to help get your instance started. The actual administration piece once the software running is pretty straightforward.
