+# List Directory
+
+To list directories recursively using bigtree, we can use the `glob` built-in Python package to extract a list of paths.
+
+```python
+import glob
+from bigtree import list_to_tree, print_tree
+
+# Get all directories recursively
+path_list = []
+for f in glob.glob("./**/*.py", recursive=True):
+    path_list.append(f)
+
+# Construct tree
+root = list_to_tree(path_list)
+
+# View tree
+print_tree(root, max_depth=3)
+```
