+[![CI](https://github.com/glideapps/zod-from-json-schema/actions/workflows/ci.yml/badge.svg)](https://github.com/glideapps/zod-from-json-schema/actions/workflows/ci.yml)
+
 A library that creates [Zod](https://github.com/colinhacks/zod) types from [JSON Schema](https://json-schema.org/) at runtime.  This is in contrast to [json-schema-to-zod](https://www.npmjs.com/package/json-schema-to-zod), which generates JavaScript source code.
