ebook and digital course

I'm looking to create an ebook and digital course as a health and wellness resource for the general public. The course should have less than 5 chapters or modules that provide useful information on how to get started with meditation. My goal is to create a product that provides a practical and systematic approach to learning to meditate. It should be engaging and easy to use, so that anyone can benefit from the information provided. Most of the content is already created - it just needs to get formatted into an ebook and have the digital course component - which would be focused on 3 days of progressive learning. The course will be housed on my squarespace website.
