Where/what is the content-manager directory?

Copy the content-manager directory to your extensions directory

I'm stuck here as I find no content-manager dir to copy. Not in the @tinymce node package. Not in my strapi installation nor in the @strapi node package. Not at the links in the README.

I'm sure I'm missing something obvious, but I have no idea what.

Would love to get this working. Thanks for making this. 👍
