autocast wake up

so i am sure this is posted somewhere but for the life of me i cant find my answer or a guide, i am completely new to tasker. so i have tried to get autocast to turn on my tv and play youtube in the morning. now i have tasker and autocast, i also have a chromecast and google home with google wifi. so far all i have been able to do is turn on my tv with my chrome cast. if some one would be kind enough to point me to a guide or help me set this up that would be much appreciated.
