Can Write "How to" or "Guide" Articles on Adobe Photoshop?

I can't be called an expert because I am still learning but I am confident about writing articles related to Photoshop "How to" and "Guide" which will be published on a website on Google. My concern is whether I am allowed to write such articles which will also include screenshots of the Adobe Photoshop UI to help my readers understand the working easily. Or do I need to get legal permission before writing and using UI Screenshots?
