How to add wifi drivers?

Hello everyone, I'm new to libreelec, I was given an old Novlex netbook with a celeron n2806 cpu, it had it's screen broken so it was removed by it's previous owner. I have tried libreelec and while all other things seems to work just fine the wifi is not. I've read on other posts that old wifi drivers are not inclueded any more. I'm looking for help on how to install the drivers for the rtl8723be or to build an image from the source that include them if needed. Found the drivers on github https://github.com/silenoth/rtlwi…aster/rtl8723be but not sure how to add them to libreelec. Any guidance will be much apreciated.
