 ### Indentation
 
-Recipe lines can be indented with spaces or tabs, but not a mix of both. All of a recipe's lines must have the same indentation, but different recipes in the same `justfile` may use different indentation.
+Recipe lines can be indented with spaces or tabs, but not a mix of both. All of a recipe's lines must have the same type of indentation, but different recipes in the same `justfile` may use different indentation.
+
+Each recipe must be indented at least one level from the `recipe-name` but after that may be further indented.
+
+Here's a justfile with a recipe indented with spaces, represented as `·`, and tabs, represented as `→`.
+
+```justfile
+set windows-shell := ["pwsh", "-NoLogo", "-NoProfileLoadTime", "-Command"]
+
+set ignore-comments
+
+list-space directory:
+··#!pwsh
+··foreach ($item in $(Get-ChildItem {{directory}} )) {
+····echo $item.Name
+··}
+··echo ""
+
+# indentation nesting works even when newlines are escaped
+list-tab directory:
+→ @foreach ($item in $(Get-ChildItem {{directory}} )) { \
+→ → echo $item.Name \
+→ }
+→ @echo ""
+```

+Desktop
+Documents
+Downloads
+
+PS > just list-tab ~
