Yoga at home

I want to try yoga but i don’t know how and where to start. I have friend teaching yoga but she’s too far away from us. She’s in Manila and since I’m based in our province we seldom see each other. I wonder if instructional yoga videos would be as effective as attending a regular yoga class. Anyway, i’m already planning to buy yoga blocks and yoga mat, maybe for the meantime i will just use instructional video at home. I hope later on I’ll be able to attend a regular yoga class.
