To be honest you don’t need to create an account on another instance. It’s a little complicated, but that’s what I understood:
Each instance it’s a website (and I’ll use website instead of instance from this point forward, but you can read instance). You can create an account and login to that website.
All the websites talk the same language, so from inside one website you can explore another, as if it was the same.
Your account, on one website, is valid on the other websites.
you may create an account on lemmynsfw.com instance and browse local, there’s a few there, but you haven’t heard it from me

Right now I’m logged on https://lemmy.eco.br/, I’m looking this post from another community (ask lemmy) that exists on another website (lemmy.ml). That translates to !asklemmy@lemmy.ml.
So, you just need to search for other instance, from inside yours.
