 1. Navigate to the file you want to work in (for example `book/some_content/overview.md`) and make sure you're in the correct branch.
 
 2. Let's create the structure of your chapter. You can start by adding a title to the section. The title is always defined in the first line of the file after the hashtag `#`. Then yo can also add sections and subsections as needed.
 
 ```
-# Chapter Title (H1)
-## Section Title (H2)
-### Subsection Title (H3)
-#### Smaller Heading (H4)
+# Chapter Title 
+## Section Title 
+### Subsection Title 
+#### Smaller Heading 
+##### Heading level 5
+###### Heading level 6
 ```
 
 3. Add some text to the sections.
