It Says i need a "subscription" to add homebrew things. I have no clue how to get one. plz help. add Close to exact steps on how to do this if you can, please.

 First, I just want to make sure you know that you dont need a subscription to create homebrew or to share it with your campaigns, only to quickly grab and use what other people have posted to this site. 

Now to answer your question: go to here https://www.dndbeyond.com/subscribe insert money.

I also am confused about the homebrew subscription thing.  I'm just asking but is there a way around paying money?

I have a question on how you use other people's homebrew content. I've been trying for days to find a way to use and see "Oath of Freedom" as a selectable subclass and I've been told various different ways to use it on my paladin. I really need help

I already tested both on a delete character. It didn't show up for either.

 It would be helpful if you linked that homebrew you're after here so others can test it and see how to get it working properly. There are 23 different Oath of Freedom homebrews on DnDBeyond's published homebrew lookup.
