Improve documentation in the README.md

[KyleJune]

I need to come up with a more structured outline on how to get started with using this framework. Right now the documentation is pretty basic.

[KyleJune]

Here are some ideas for sections.

• Creating API and UI routes
• How to build
• How to use dev server
• How to deploy
• Serving static files
• Oak middleware
• Logging
• Configuration
• Adding esbuild plugins
• Adding context
• Using react libraries
• Rendering markdown or raw HTML
• Testing
• Examples
