How to connect a Bluetooth Speaker

Hello people,
first of all im from Germany and i appologize for grammatical fails.
I want to connect a bluetooth speaker to my Volumio which runs on a Raspberry 3. As you know it has an inbuild Bluetooth receiver. So how can i actually use it. There is no Function for this on the web interface. I am not a pro in linux so direct comands would be nice so i dont have to search alot.
I also searched for volumio pugins but there are none?

Thanks for the help.

There is no oficial bluetooth support in Volumio, but a search of the forums leads here.

Thanks i will try it out. Looks just like what i need. Any Idea when Volumio support Bluetooth by default?
