 You can generate an example config by running [`goreleaser init`](/cmd/goreleaser_init/) or start from scratch.
 
 You can also check if your config is valid by running [`goreleaser check`](/cmd/goreleaser_check/), which will tell you if are using deprecated or invalid options.
+
+## JSON Schema
+
+GoReleaser also has a [jsonschema][] file which you can use to have better editor support:
+
+=== "OSS"
+    ```sh
+    https://goreleaser.com/schema.json
+    ```
+
+=== "Pro"
+    ```sh
+    https://goreleaser.com/schema-pro.json
+    ```
+
+You can also generate it for your specific version using the [`goreleaser jsonschema`][schema] command.
