Hello and welcome, I hope you enjoy your stay here.
I am pleased that you want to learn more about Islam from its sources. Perhaps, we can help each other out as I myself am looking for some good Christian sources. At the moment I can think of one good website which includes commentary on the verses in the Quran to help you better understand its context.

I am sure that brothers and sisters will later add to this and provide you with some more information but hopefully, this is a start.
