I need an impactful 'How to' Infographic

Information for the business: Online health and fitness portal
Industry: Sports and Fitness
Design details: I am looking for a simple, impactful info graphic which explains to the audience (who will be a mixture of health and fitness professionals and web developers) how to embed their class timetable (hosted on my website) into their own website. I have a list of instructions (attached) and some screenshot examples of what the user will see and these will need to be included for clarity.
Target audience: Health and fitness professionals who already have their own websites
Ideas for the visual style: Fairly neutral as the range of the audience is wide.
Things to avoid: Making it too busy - needs to be simple, clear and impactful.
Where the design will be used: Social media, website, online newsletters
Extra notes: Have a look at my website - www.myfitnesstimes.com to get a feel for the branding etc. However, this should not be followed to closely as I do want to make it slightly more neutral.
