I have to create an onboarding document for new users of my product so that they have a smooth experience of using it. I need to create a catchy document with the flows of how to use the product. Please let me know if there are any tools available online for some infographic stuff that I can use for the same. I am currently taking screenshots to develop the flow and and using powerpoint to create the document. But the results have been disappointing. The screenshots are very dull and hardly noticeable. I hope someone can help me out here.
