+If you have plain-text json configs, theme templates, or templates for usage for your plugin of any description you should have those files be in here.
+Those files will be pulled into the zip during the build process and included with the upload. Example: CssLoader with it's themes in "default/themes" would have the "themes" folder will be added alongside with the dist folder, main.py, LICENSE and README files in the subfolder of the zip containing the plugin.
+Files can also be put in here such as a config, just keep in mind that they this directory cannot be utilized to put files in arbitrary locations, just within the extracted root folder of the plugin, ex: CssLoader has "defaults/themes/..." setup in it's repo, but when packaged to go to the store, the file structure will be:
+
+- LICENSE
+- README
+- dist
+  - index.js
+- main.py
+- package.json
+- plugin.json
+- themes
+  - exampletheme.css
