Thanks for the initial work on this PR!

I added a few comments, if anything is not clear don't hesitate to ask me 🙂.

I think this page is too verbose.

I think the best it to reduce all the content to just a list with a quick description, default value, etc (vite example).

I'd put example only on very esoteric configuration entry (that IMHO we don't have yet).

Let's go ahead with something like:

# Configuration

short desc + snippet to display where to import TuonoConfig

## vite

Mention about that this is a wrapper to some of vite options

### vite.option1
short desc

### vite.option2
short desc

### vite.option3
short desc

I used the template you described above, with just one additional section - "Using Vite alias for Path configuration"

I replaced this section with a note inside "vite.alias" section.
This note informs the user that a working example can be found in tuono-tutorial template and in the documentation code.

In the future, if users encounter trouble configuring the alias property, I would consider adding a section similar to the one you proposed on a standalone page, turning the 'Configuration' nav option into an accordion, like 'Getting Started,' 'Tutorial,' and others.

Additional changes

• I noticed a problem in the MDXProvider configuration:
  (bold item were printed inside a <div /> tag so I replaced it with a span
• reword and format content
• applied prettier format

Looks good to me.
Thanks for taking care of this!
