Following technical writing best practices, it's always better to specify communication to a single person.

I edited this part to suit the best practice, and I also made some grammatical changes.

Here are a few additional things that can be added, but I need the right information from you.

• I can add 2-3 sentences in the introduction for Personal Assistant. A brief explanation from you would be needed to educate the end user of what is primarily a Personal assistant (as regards crayon), and not just the goal of a Personal Assistant. Is there a problem in finance that the Personal Assistant is solving? What is the leverage of using Crayon's Personal Assistant that other counterparts don't provide? Those details can come together in 2-3 sentences.
• A heading for 'Prerequisites' should be added, and not just the 'Getting Started' Link. What tools should the dev have before building this assistant?
