> @ build /.../example-vanilla/website

for now I'm doing a manual merge afterwards...

e.g. I run docusauruns and storybook build separately and then have an additional step afterwards to merge and publish them...

it's a good enough workaround for me... still a pitty it doesn't work out of the box

PS: feel free to close it if you think it's something docusaurus should/will not support

Hey @daKmoR,

Sorry, I missed this.

I think this is related to #525.
Nested folder named "static" inside static files folder causes build error

Same issue using storybook, but that issue didn't have any reproducible issue. So we'll use this issue instead.

The error that I got was different though from what is told in this issue. It's similar to #525

P.S: This will work on v2 (we will post a blog about it soon).
