Peace be upon you O Brother in humanity who came with the great happy news which made my day.
All praise is to Allah (god) who made Universe and everything in it.
As brother Ayman1 said, the way we enter to the beautiful life of Islam is by saying Shahada infront of 2 witnesses, in a clean state. After that, move forward step by step. Read more books and read the Translation of Quran. Learn how to pray. (Please note that you should pray after entering Islam 5 specified times in a day. If you do not know any duas of Surah al-Fatiha and any other small surah yet, just say Laa-Ilaaha Illallahu Muhammadharrasoolullah or any good Kalimah like that for example Alhamdhulillah (thank is to Allah), Allahu Akbar (Allah is the Greatest) in all the situations of Prayer).
Allah mentions in Surah Al-Baqara (The Cow) in Noble Quran, "On no soul doth Allah Place a burden greater than it can bear............" (2:286).
So take step by step my brother. Be hurry to take Shahada, but do not be in a hurry to learn and do all the things in one day or week. It will take time.
Also one thing. Please remember me in your duas because when you take Shahada, you will be just like new born baby who has not even a single sin. MashaAllah.
Peace be upon you.
Your brother in humanity and who hope to be your brother in Islam very soon,
