Could you also help to run a check on the asset names and what's referenced in the docs/ folder? For example, in my local version of the code, I now have 63 hits for .png but only 50 images in the .gitbook/assets folder. Just wondering if we missed something else on the first import. Other than this, LGTM. Thank you!

Some are used more than once so it won't be a 1:1 relation but rather a 1 png to many references relation.
