# VS Code Extension 🔌

The Sling VS Code extension provides schema validation and language server features for SlingData.io configuration files.

## Why Use It

This extension enhances your productivity when working with Sling configuration files by offering:

* **Auto-detection** of Sling configuration files (e.g., pipeline.yaml, replication.yaml, spec.yaml).
* **Schema validation** to ensure your configurations adhere to the correct structure.
* **Auto-completion** for properties, values, and expressions.
* **Hover information** providing inline documentation.
* **Diagnostics** for identifying errors, warnings, and suggestions in your configs.

These features help you write valid and efficient Sling configurations, reducing errors and speeding up development!
