Vibrato is the undulating pitch given to a note by the left hand. The finger stays in contact with the string and doesn't slide on the string at all.
So our first rule is to go high up the neck and play it there.
On our sustain sheet, we explain how vibrato can make a note seem longer and livelier. It breathes life into a melody.
The rule we use in hago is that if it's a long note, we use vibrato. Simple as that. And indeed it becomes second nature and almost impossible not to do it!

The nicest vibrato starts gently and builds slightly in intensity and frequency - just listen to a good flautist play a melody and that's how to do it.
Vibrato that's too fast and starts instantly makes the guitar sound like a French Chanteuse, and it really doesn't suit most music (or most audiences!)
If you're nervous and it's a hot day, watch out - the 4th string will require some intense "digging in" to make the vibrato sing, and if you're not careful, then the first note you attempt on the 3rd (monofilament) string will be greeted with a very slippery string. You might find your finger actually sliding and possibly missing the fret.
