 ## About StackQL
 
-StackQL is a utility which allows you to query and interact with cloud and SaaS resources in real time using SQL grammar.  StackQL supports a full set of SQL query/DML grammar, including `JOIN`, `UNION` adn subquery functionality and supports mutation operations on cloud and SaaS resources such as `create`, `update` and `delete`, implemented as `INSERT`, `UPDATE` and `DELETE` respectively.  StackQL also supports grammar for performing lifecycle operations such as starting or stopping a VM using the `EXEC` statement.

+## Code Linting
+
+To maintain code quality and consistency, we use `ruff` as the linter for this project. `ruff` offers fast performance and a comprehensive set of linting rules suitable for `stackql-deploy`. You can run the lint check as follows:
+
+```bash
+ruff check .
+```
+
+Note: If you need to install ruff, you can do so with `pip install ruff`.
