+- Automatic mode activation for `.toml` files (e.g., Cargo.toml, pyproject.toml)
+- Line comment support using `#` character
+- Consistent visual appearance with yaml-mode and json-mode
+
+
+### Usage
+

+;; Load the mode
+(ql:quickload :lem-toml-mode)
+
+;; Mode activates automatically for .toml files
+;; Or manually: M-x toml-mode
