The digital garden uses 11ty when building the site, and markdown-it for rendering markdown to html.
If you want to configure either the 11ty build pipeline or the markdown rendering engine you can do so in the
src/helpers/userSetup.js file. There should be two functions there:
userEleventySetup(eleventyConfig). These will be called after all the default setup has been processed, and allows you to do modifications on both the eleventy config and the markdown-it instance. For examples on how these are configured, you can have a look in the
.eleventy.js file in the root directory of your site.
