Know how to tune your guitar
This is the most important thing you will learn in the beginning. If you cannot tune it, you cannot play it. Modern technology has made it very easy for us to clip a tuner on the headstock and tuneup anytime we need it. Take the time and learn what note each string is tuned to. The Internet can help you in the beginning to familiarize the sound of how each string should be for standard tuning
Know your fretboard
This will take time but it is a tool that will serve you for the rest of your playing years.
If you don’t know the notes on your fretboard for each string and positioning, this will make it difficult to go beyond first position chords. As a seasoned guitar player I am currently learning the Mandolin. For those of you who do not know how the mandolin is tuned, it is upside down, or backwards from a guitar. I am having to learn the fretboard all over again and yes, it is challenging.
Learning your fretboard will also open up a whole new world of being able to play chords in a different voicing. Chords can be played in more than one way in different positions on the neck. Many songs are written where the cords are not in first position and that’s what makes them special. So I stress, learn your fret board.
Learn the anatomy of your guitar
Know what the bridge, nut, frets, headstock, pickups, and selector switch, (if there is one). Especially on electric guitar there are many things to know.
