Link for a Step-by-Step to install Avada

Hi, All, recently purchased a theme (Avada). Please can someone guide me as to how i can install the theme on my wordpress page or provide a credible Youtube Link,

Many Thanks!

Thank you. I’ll check it now.

I noticed that my Avada.Zip file is smaller than normal. Please can some confirm that I have the right download? I checked the Link and in the video it was about 25MB and mine looks smaller at 5.5MB.

Also, the is large, what is it meant for?

Many thanks for your reply.
