+
+* `/blog/` - You can delete the directory if you do not want/need a blog. More details can be found in the [blog guide](https://docusaurus.io/docs/blog)
+* `/docs/` - Customize the order in sidebars.js. More details can be found in the [docs guide](https://docusaurus.io/docs/docs-markdown-features)
+* `/src/` - You don't have to strictly put your non-documentation files in here but putting them under a centralized directory makes it easier to specify in case you need to do some sort of linting/processing
+  * `/src/pages` - More details can be found in the [pages guide](https://docusaurus.io/docs/creating-pages)
+* `/static/` -  Any contents inside here will be copied into the root of the final `build` directory
+* `/docusaurus.config.js` -  This is the equivalent of `siteConfig.js` in Docusaurus v1
