starting in Islam

I am a Christian unfortunately, but I am reading the Quran and I want to convert to Islam because I believe that the Quran is the only truth in this life, praise be to Allah.. I would like to start praying even if I have not converted yet, is this possible? I am also learning the salah prayer, I have memorized al-Fātiḥa, but I can't memorize the rest of the prayer.. do you have any advice? praise be to Allah
