Find a friend to mentor, guide and coach you.
If you can find a friend, or coworker, relative, someone's friend of a friend.
You have to know somebody, and they are usually always looking for someone to go and shoot with.
Most of the time they will be more than glad to help and show what they know.
It usually doesn't take long to show you the basics, so even if you have to take notes, do it.
Also try to find an archery shop and go there during off hours where they aren't busy and you will get enough instruction to get you going.
Also read all you can to learn about arrows, and spine vs. bow weight and draw length, anchor points, release aids or tabs etc.
All important to know to have a correct set up for accuracy.
