I tried a 4 year old „Introduction to cachly“ on YouTube, made by a Scotsman, and although a bit older, it helped here and there. What helped even more was asking a friend to try out logging his cache and him not wondering about the funny things that might happen - so I could log found, post DNF, add a coin and remove... - kind of personal intro. The rest worked out in the field then, asking my friends to be a bit more patient as I needed to find out how things worked...
