How could my partner and I go about starting an Only Fans?

We’ve both talked about it alot, we’re both extremely comfortable with eachother, we’ve thought of clever ways to hide our identities, and this is something we’re genuinely considering just for extra cash lmao. For those that have done it - or currently do it, what’s it like? What are some BIG things we should know going into it?
This not a promotion by any means being that we haven’t even started the account yet 😂
