Hi korhanerel, thanks for the question, and yes, this is definitely something we're working on at the moment. We're trying to make the whole process of working with Bela as smooth as possible and so are putting a lot of focus on the documentation and the workflow with the browser-based IDE.
There are actually instructions for updating Bela on the wiki but they were a little hidden. I've just moved them to a move prominent position.
