Information Architecture -> docs that are easier to use

[mjang]

We want to help you take full advantage of NGINX in the shortest possible time. In support, we're looking to update our Information Architecture. With a consistent architecture, we want to make it easier for you to find what you need.

We know that "everyone" is looking for docs which cover their use case. To get there, we're thinking about populating our home page with common use cases. When you select those use cases, you'll see:

• Steps to get started, with an overview
• Detailed options, organized largely on the Diataxis framework, which includes
  • Tutorials
  • How-to guides
  • Explanation
  • Reference

In the spirit of open source, we will share this discussion with you, our users.
