How to wash your hair with a weave?

I just got my hair extensions in a few days ago. It's straight hair and I have straight hair. I don't have black hair and it's sewn in. How do I wash it properly with what products and such? My weave isn't heavy and I don't have a lot of tracks (I don't have a full head). It's all human hair and the length is past my boobs. Please help!
