+# 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.
+
+All lttle resources are defined using YAML files. To get started, we have prepared a YAML schema to facilitate resource creation. You can find it here: [resources.json](https://raw.githubusercontent.com/lttle-cloud/ignition/refs/heads/master/schemas/resources.json) or you can directly reference it via: [resources.lttle.sh](https://resources.lttle.sh).
+
+To make working with YAML files easier, you can set up your code editor or IDE with the following extensions:
+
+## 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.
