To become Muslim, all you have to do is believe in your heart, and pronounce the Shahadah (testimony of faith);
If you're ready now, you can recite this with your heart and tongue while having faith in the Lord of the Worlds;
(in arabic recite: ) Ash hadu an laa ilaaha ilAllaah, Muhammadun Rasool Allaah.
I bear witness that there is none worthy of worship except Allah, and Muhammad (peace be upon him) is the Messenger of Allaah.
Once you recite this, you are Muslim, you've joined the biggest faith community in the world! :) And we welcome you to Islam. I think you already know this, that there is nothing less than Paradise for the one who submits his or herself to Allah, and dies as a believer. And that all your previous sins and mistakes have been forgiven.
