PieFed help

I want some links to community posts in my community sidebar (e.g. to posting guidelines, resources etc) but which people can interact with even if they're on a different instance, i.e. comment, vote, etc.

At the moment, I link to the same page twice in two different ways:

• plain URL - https://piefed.social/post/992414 (but if they're on a different instance, they won't be able to comment etc)
• Lemmyverse.link - https://lemmyverse.link/piefed.social/post/992414 (which is fine, I think... as long as lemmyverse.link exists)

How should I do it?

(This isn't necessarily a PieFed issue, more an entire Fediverse issue. I'm still not 100% clear how to link to Fediverse content in a way that a Fediverse member can actually use.)
