Hello there... for a simple learning the verb "voy", is usefull when your using it to express an action, like for example if you want to say: Im going to cook, Im going to the school, Im going to bed, Im going to leave now. So all this sentences express an action "going", which is pretty much the same on spanish. Review with going/voy: Yo voy a comer ahora.

Voy means nothing but "go" in the future, only for the pronoun "I". The present is "IR" Yo voy = I'm going, I'll go [it depends if you're using the future or the continuous... Yo voy a la panaderia = I'll go to the bakery If you'll use "she'll go", it's "ella va"

Cherry answered this well. But also voy is great when used in front of another verb. Yo voy a comprar una bebida = I am going to buy a drink Yo voy a leer los periódicos = I am going to read the newspapers
