+> How to create a MkDocs site
 
 This is a summary of the tutorial on [mkdocs.org](https://www.mkdocs.org/).
 
 
+### Basic structure
+
+This is the simplest MkDocs site you can make, with a config at the root and a homepage in the `docs` directory (default). Usually on `master` branch. 
+
+```
+mkdocs.yml
+docs/
+    index.md
+```
+
+The steps below start with that and extend it to more pages.
+
+
