So far for me the process is very convoluted:

1. I go to https://browse.feddit.de/ and find the community.
2. Then I need to copy it’s name.
3. Then I need to go to my particular instance (lemm.ee)
4. Then I type manually in my browser address bar lemm.ee/c/<communityname>
5. Then I go back to https://browse.feddit.de/ and copy the address of the original instance of the community.
6. Then I go back and add the original instance address to already typed thing in step 4 like this lemm.ee/c/<communityname>@<originalinstanceofcommunity>
7. Then I can finally subscribe!

Oh my God! Please, tell me there’s a better way of doing this!

EDIT: There is a better way! Solution is to … use the search function in your instances home page and select community (if it exists already) and search. This way I don’t need to go to browse.feddit.de anymore. And links will take me straight the the communities “reflection” in my own instance, where I can subscribe.
