In reply to The Lemming:
There is a very good book called The Beginners Guide to Da Vinci Resolve 16 by Paul Saccone and Dion Scoppettuolo which goes through, step-by-step, how to edit with the programme. Its one of a series of books which also cover advanced editing, colour correction, fairlight audio post and fusion visual effects.
I just hope your computer has more power under the bonnet than mines has!
