Magento 2.3 Upgrade - AD0-E703 Adobe Magento Commerce Developer Expert (Formerly Magento 2 Certified Professional Developer)

I would like to offer an overhaul to the formatting and extend on the already amazing work that has been done here. From my years of experience and recent examinations I wanted to add the following which proved beneficial to myself:

• Apply human friendly formatting and make more readable to the user.
• Extend on the existing content to make more readable.
• Apply examples and code snippets to existing content.
• Apply more markdown formatting + use of imagery.
• Extend on subjects needing more explanation. Namely sections 7, 8, 9, 10.
• Add more links as references.
• Add additional sections about Multi-store, Multi-website, Indexers. These are merely notes and detailed insight into an area of Magento I believe needs explanation. You are free to remove if not relevant.
• Upgrade as of Magento 2.3 standards
• Change the name of the exam since Adobe's take over. AD0-E703 Adobe Magento Commerce Developer Expert (Formerly Magento 2 Certified Professional Developer)
