We have a guide for this.
Hopefully it helps people make custom NIP-05s 😃.

Nice! But even if you don't want to host your own file, get a free or paid NIP-05. Seeing "important" people posting on nostr with an identifier which doesn't resolve makes me think their account is fake or that they don't care about their "identity".
We agree, when we were first fiddling around with NIP-05 we found that most guides, and documentation might not be accessible to less tech inclined people.
So we made one that was hopefully more beginner friendly.
It did take a while to figure it out but we did 😃.
We even list some of the NIP tools in case people want to utilize those instead if they find our guide difficult.
We think NIP-05 is a nifty little feature, and want to help everyone utilize it 👀.
