Gonna be honest, first version of wrenches.io was really bad.
I got some feedback from first users and other indie hackers here and changed these things:
Removed an extra UI page that user had to go through before seeing the actual content (now it shows the navigation first and when you scroll down it shows content right there)
Separated the main content into 7 different pages. After @harrydry shared tips for better SEO that sounded like a right thing to do in order to score more places in google search results with my content
Changed styles and colors, made sidebar less prominent and more useful (it now has links to all the main steps of product creation)
