Depending on the kit, usually bolting them up is very easy, however the hard part is to adjust the swing and lift with them for guard clearance and easy closure, also extending the wireing loom takes a little time.
Very doable DIY but will need a soldering iron, a second pair of hands, good sockets and a bit of experience with working on car paneling etc etc...
I deal with any Scissor door kits for hondas from the usa
