HTML Documentation with Video Tutorial

Hi there,
My query is about WordPress Theme documentation.
I want to embed videos in my HTML document.
What I want to say is I will create HTML document for my WordPress theme and give detailed instruction using videos instead of text.

An example could be:

**About Section Customization **:
Here is a demonstration video on how to customize the about section: (embedded video goes here)

I wouldn’t like to give text description. Just a short description and then video tutorial.

Is it allowed to do so?

Please, do help me.
Thanks much for your time.
