+
+```python
+# List files in root directory
+await nc_webdav_list_directory("")
+
+# Browse a specific folder
+await nc_webdav_list_directory("Documents/Projects")
+
+# Read a text file
+content = await nc_webdav_read_file("Documents/readme.txt")
+
+# Create a new directory
+await nc_webdav_create_directory("NewProject/docs")
+
+# Write content to a file
+await nc_webdav_write_file("NewProject/docs/notes.md", "# My Notes\n\nContent here...")
+
+# Delete a file or directory
+await nc_webdav_delete_resource("old_file.txt")
+```
