[Support request] How to use the free and premium GeneratePress tools for building New Websites?

hi there,

Could you guide me on what are the best places I should start learning from if I would like to learn how to use the free and premium GeneratePress tools for building new websites?

The documentation and YouTube channel would be a good starting point:
https://docs.generatepress.com/
https://www.youtube.com/c/generatepress

Also, if I import a new pre-build starter theme from your site library, will it be easy to change it after a while to a new pre-build starter theme from your site library?

Take a look at this:
https://docs.generatepress.com/article/using-the-site-library/
https://docs.generatepress.com/article/using-the-site-library/#removing-an-imported-site

Do you recommend customizing the theme I use and adding extra features later on? 😀 Or build the site I envision on my own from scratch?

I cannot answer this question as it depends on what you are trying to build and it’s totally up to you.

If something in our site library works for you then that would be a good starting point.
