followed the quickstart instructions yarn add typedoc typedoc-plugin-markdown@next typedoc-vitepress-theme@next --dev to get...

p.s. progress with typedoc-plugin-markdown alone

@0xpatrickdev suggested, in packages/zoe:

yarn add -D typedoc typedoc-plugin-markdown
yarn prepack
yarn typedoc --plugin typedoc-plugin-markdown --out typedoc-gen src/*

# see markdown in typedoc-gen

and I was able to reproduce his results.

It lacks navigation links. @0xpatrickdev suggested https://www.npmjs.com/package/vitepress-sidebar looks like a popular approach.

fixed in #1038

let's track #1041 under #1031

and I think we talked about making #1046 a lower priority

[dckc]

We're reconsidering this approach: #1032 (comment)
