By default the toolkit will look for an <code data-paste-element="INLINE_CODE" data-paste-core-version="20.7.0" class="css-1kwd7zr">assets/</code> or alternatively <code data-paste-element="INLINE_CODE" data-paste-core-version="20.7.0" class="css-1kwd7zr">static/</code> folder.

So for example a file under <code data-paste-element="INLINE_CODE" data-paste-core-version="20.7.0" class="css-1kwd7zr">assets/index.html</code> would result in a path of <code data-paste-element="INLINE_CODE" data-paste-core-version="20.7.0" class="css-1kwd7zr">/index.html</code>.</p><p data-paste-element="PARAGRAPH" data-paste-core-version="20.6.0" class="css-tcah8o">Assets are a great way for you to also host resources that you want to access from your Functions that are not other Functions or should not be available to the public. For example configuration files or other JavaScript files you want to <code data-paste-element="INLINE_CODE" data-paste-core-version="20.7.0" class="css-1kwd7zr">require()</code>. You can store those as <em>private Assets.</em></p><p data-paste-element="PARAGRAPH" data-paste-core-version="20.6.0" class="css-tcah8o">To mark an Asset as private, include <code data-paste-element="INLINE_CODE" data-paste-core-version="20.7.0" class="css-1kwd7zr">.private.</code> in the filename.
