 The Things Stack uses the `github.com/TheThingsNetwork/lorawan-frequency-plans` as default source for fetching frequency plans. Therefore, contributing to this open source repository makes frequency plans automatically available to Stack deployments with default settings. You can contribute by submitting pull requests. Are you new to GitHub? That's great! [Read here about pull requests](https://help.github.com/articles/about-pull-requests/). Please also use the editor settings as defined in `.editorconfig`.
 
+There are json schemas available for all configuration files. These define files structure and make it easier to fill them in. To enable them in `VSCode` add the following to your `settings.json` file. 
+```json
+{
+  "yaml.schemas": {
+    "schema.json": "frequency-plans.yml",
+    "end-device/schema.json": "end-device/*.yml",
+    "end-device/modifiers/schema.json": "end-device/modifiers/*.yml",
+    "gateway/schema.json": "gateway/*.yml",
+    "gateway/modifiers/schema.json": "gateway/modifiers/*.yml"
+  }
+}
+```
