+# Configuring your editor
+
+To be able to benefit from YAML schema validation and autocompletion, we recommend setting up your code editor or IDE as described below.
+
+## Visual Studio Code
+
+Install the [YAML Language Support from RedHat](https://marketplace.visualstudio.com/items?itemName=redhat.vscode-yaml) extension for better YAML syntax highlighting and validation.
+
+Create in the `.vscode` folder a `settings.json`, file with the following content:
+
+```json
+{
+  "yaml.schemas": {
+    "https://resources.lttle.sh": "/*.lttle.yaml"
+  }
+}
+```
+
+This will also work for Visual Studio Code spinoffs like **Cursor**.
+
+## Other Editors / IDEs
+
+Check your editors documentation on how to add schema definitions for YAML files.
