First thing to do is learn a few chords and some basic scales. The first chords to learn are Eminor and dmajor as they are easier to hold down.

Scales will help you gain flexiblity and strength in your hands. A good first scale is the penatonic minor, it’s also used for most modern music too. Once you’ve got comfortable with scale look into how they relate to chords and the keys of music.

I hope this helps
