+# Overview
+
+The [Interoperability Test Bed](https://joinup.ec.europa.eu/collection/interoperability-test-bed-repository/solution/interoperability-test-bed) is pleased to announce the availability of the latest release of its JSON validator.
+
+# Usage
+
+The primary means of using the validator is via Docker image, either directly to create a container, or as a base image for custom validator images.

+
+Details on configuring and using the validator are provided in the [JSON validation guide](https://www.itb.ec.europa.eu/docs/guides/latest/validatingJSON/index.html), with additional details for on-premise installations in the [production installation guide](https://www.itb.ec.europa.eu/docs/guides/latest/installingValidatorProduction/index.html).
+
