How to install aurora store?

How to best install aurora store?

I tried using obtainium. I selected aurora store from obtainium's crowdsourced app list but obtainium gave error 429 (I think). Edit: now works!

What is the recommended way to install so it will stay up to date?

Edit: obtainium and using the crowdsourced list works fine now! It seems to have been some temporary thing, maybe ddos or just an outage?
