Storybook Astro — Community Storybook Framework for Astro

If you're using @astro.build you may have noticed that you can't use @storybook.js.org to document your Astro components.

Things have changed lately thanks to github.com/slawekkolodz....

I'll give storybook-astro.org a try this week and so should you 🎉

When I use a second or third language, I can't express my thoughts or other people's thoughts accurately. It feels really uncomfortable. I get this frustration that slowly builds up inside me. And I know this comes from my own lack of ability.
