Future updates?

Just a curiosity for the moment but when Kodi gets updated, is there a way to update from within the app or do I have to update it using the same method I used to install it? I’m not complaining, it’s just by that time i would have totally forgotten how I did it and would have to find and follow the installation instructions again. I would be so much easier if you could update from the app but I get that may not be possible due to the nature of WebOS and the way Kodi has to be installed.
