There are instructions provided with the Aeropress and these are enough to get you started.
That's the first step: get started; the rest is up to you and experience. You may or may not make amazing coffee the first time but you will get there.
Next step is to do some reading here on Coffee Snobs and elsewhere on the net (google 'aeropress recipes') But like nearly everyone on this forum, it doesn't how much you are told, the fun is in learning for yourself.
Some other guidelines.
1. Get the best beans you can. 'Well known' does not mean best.
2. The scoop/spoon that comes with the Aeropress holds enough coffee for 1 cup so use that as your measure.
3. Stop grinding when all the beans you have measured into the grinder are ground.
4. Don't use boiling water; either bring it to the boil and let it cool for a minute or stop it just before it boils
