@jagged_circle You don't install a Bluesky instance, rather you host your own PDS, or your own web client, or the feed part. It's all a mess and the latter has very high system requirements for one to self-host from what I understood. Basically, it's impossible if you're not a company with the willing and the money to do it.
If decentralization actually happens on Bluesky, it will be more confusing for the average person than with something like Mastodon.
