 If you want to add an optional folder structure to your documentation, you can use the following command to generate a tree-like structure.
 
 ```bash
-find . -type d ! -path '*/.*' | sed -e "s/[^-][^\/]*\// |/g" -e "s/|\([^ ]\)/|-\1/"
+git ls-tree -r --name-only HEAD | sed 's|[^/]*|   &|g'
 ```
 
 Example output:
 
 ```text
- |-resources
- | |-images
- | |-diagrams
- | |-scripts
- |-know-how
