Social proof section with React

What I have learned:

I learned how to create a React app, use props to pass information from one component to another and how to deploy it on GitHub-Pages.

My questions to the community:

Is my approach correct? There are 2 branches in my repo: main and gh-pages. Should/do I merge the branches? Is that even possible in this case?

I am very happy about any advice!

Best regards Thomas
