In the Jekyll config, source is set to source: ./jekyll
A collection that lives in that source ./jekyll/_work
Netlify CMS Config inside admin folder ./jekyll/admin/config.yml
Collection path references from the admin config folder: "_work"
The admin CMS actually creates this folder in the root of the repo with the html file inside of it
Does the admin config path have to include the Jekyll source again e.g. folder: "../jekyll/_work"
The folder paths in the Netlify CMS config.yml
are relative to the root of your repository.
folder: "jekyll/_work"
media_folder
is also relative to the root of the repository
