+# OpenAPI Overlay 1.0.x JSON Schema
+
+Here you can find the JSON Schema for validating Overlays of versions 1.0.x.
+
+As a reminder, the JSON Schema is not the source of truth for the Specification.
+In cases of conflicts between the Specification itself and the JSON Schema, the
+Specification wins. Also, some Specification constraints cannot be represented
+with the JSON Schema so it's highly recommended to employ other methods to
+ensure compliance.
+
+The iteration version of the JSON Schema can be found in the `$id` field.
+For example, the value of `$id: https://spec.openapis.org/overlay/1.0/schema/2024-10-17` means this iteration was created on October 17, 2024.
+
+## Contributing
+
+To submit improvements to the schema, modify the `schema.yaml` and add test cases for your changes.
+
+The TSC will then:
+- Run tests on the updated schema
+- Update the iteration version
+- Publish the new version
+
+## Tests
+
+The [test suite](../../tests/v1.0) is part of this package.
+
+```bash
+npm install
+npm test
+```
+
+You can also validate a document individually.
+
+```bash
+node scripts/validate.mjs path/to/document/to/validate.yaml
+```
