Midi setup in Ableton

Hello folks

you’ve probably had loads of similar requests but bear with me

don’t really understand midi but I want to run my BB with ableton live lite 10 that I have installed on laptop,
I have the specialised midi lead running into a standard midi to usb cable that goes into laptop
what settings do I need to input on BB and also how do I need to configure ableton so the 2 sides can communicate with each other

would be eternally grateful for anyone with a bit of patience to walk me through the process

many thanks in advance
