 ## Features
 
 This extension is designed to **highlight docstrings** in **Python code**, making it easier to read and understand the source code. It does not provide any support for editing or creating docstrings. It is optimized for the **Google**, **NumPy**, and **Sphinx** styles docstring format, though it should work partially with other formats as well.

 > **Technical Note**: The highlighting uses the VScode TextMate grammar injection feature, which means that it is compatible with any color theme and should not lead to performance issues (i.e. no custom scripts is executed). The extension uses a custom  grammar to match the docstring patterns and inject the appropriate scopes into the code editor.
