 JSON schemas for Kometa YAML files
 
+How to:
+
+Add this as the first line in your `config.yml`:
+```
+# yaml-language-server: $schema=https://raw.githubusercontent.com/Kometa-Team/Kometa/nightly/json-schema/config-schema.json
+```
+[change `nightly` to `develop`, or `master` if you wish]
+
+Then open your config file in an editor that supports the use of JSON schema.
+
+For example, VS Code with the Red Hat YAML extension.
+
+This will give you context-sensitve hints and auto-complete for much of the Kometa `config.yml`
