Hey there;
Couldnt find a correct place to request.
I saw there’s how to section but no info for transmission.
It would be very good that can somebody prepare a how to instruction for Transmission to install and other details.

You can install it from the OSMC App Store

Thanks for suggestion.
But, again it would be good to have kind of instruction.
I already installed via OSMC app store.
But, there’s no interface after install.
So, how can I configure it ?
Checked also enabled and disabled add-ons but without success.

Besides, all other post about Transmission mentioning do it by sudo comments.
So which way is the most suitable ?

Maybe this will help:
