Just Ordered A Pebble Time

As the title says it, I just ordered a pebble time, refurbished one of course, after a long time of debate and posts here in this sub, thanks for everyone who advised me on what to get. This is my first smartwatch, never had one before. Is there anything I need to know? Like what not to do, can I leave it charging overnight, etc or am I just overexcited.
