If you can find a local teacher to give you a few lessons, that's definitely the best. If that's not an option, I know a few people that liked yousician for getting started. There's lots of good self learning content on YouTube and such, but particularly if you don't have any experience with other instruments then a teacher will be a huge help. A lot of learning an instrument is knowing how to practice, how to recognize what you need to work on, identitying bad habits, etc. Having the advice of someone with experience is very helpful in that regard.

You definitely don't need to learn to read sheet music. Unless you are into classical or jazz, you will probably never use it. Start of with chords and chord sheets. Learn to play songs you enjoy. When you have the basics of chords, move on to tabs, lead lines, scales, and improvisation.
