Oh, some clients don't make it easy with publishing posts 🗡️
Here is a proper link: https://blog.getalby.com/what-is-alby-hub

Alby Hub is open to public!
Alby Accounts (with getalbycom lightning address and some other services) are invite only.   

 Awesome. Got it. 

Please can you link me to the github link for adding community repository to Umbrel? 

Many thanks in advance.
