 Visual Studio Code and PhpStorm are two popular editors that work out of the box. However, some editors require a plugin installed, and not all editors recognize the `$schema` property. Check your editor's documentation for details. Additionally, [SchemaStore.org](https://www.schemastore.org/) and [JSON Schema](https://json-schema.org/implementations.html#editors) have lists of editors known to have support if your current editor is unsupported.
 
+## Local Development
+
+You may wish to update one of the schemas to conform to a new change in the structure. In order to do this you'll want to be able to see how your changes impact how your IDE displays schema information.
+
+To allow this you will need to:
+
+-   update your theme's `theme.json` to reference the _local_ version of the schema file:
+
+```json
+{
+	"$schema": "file://{{FULL_FILE_PATH}}/schemas/json/theme.json"
+}
+```
+
+-   update your block's `block.json` to include:
+
+```json
+{
+	"$schema": "file://{{FULL_FILE_PATH}}/schemas/json/block.json"
+}
+```
+
+Be sure to replace `{{FULL_FILE_PATH}}` with the full local path to your Gutenberg repo.
+
+With this in place you should now be able to edit either `schemas/json/theme .json` or `schemas/json/block.json` in order to see changes reflected in `theme.json` or `block.json` in your IDE.
