Multiple errors on bundle exec jekyll serve

I believe I installed the theme correctly but am getting multiple errors when running 'bundle exec jekyll serve' (see below) - default and home layout pages not found, tufte.css not found.

Like the Tufte-Jekyll theme, this one only provides the index and page layouts, so you will have to edit your site to match. Also, the default css is not css/tufte.css but assets/css/main.css.
