+# Open API spec
+
+The `rest-service-open-api.yaml` defines the api contract for running table
format conversion using XTable's REST service.
+This spec is still under active development and is subject to changes.
+
+## Lint
+
+To make sure that the open-api definition is valid, you can run the `lint`
command:
+
+This will first run `make install`, which in turn will create the venv (if
needed) and install openapi-spec-validator
+```sh
+make lint
+```
+
+if you want to wipe out the venv and start fresh run make clean
+```sh
+make clean
+```
+
+## Generate
+
+Note: You’ll need the OpenAPI Generator CLI installed and on your `PATH`. You
can install it using Homebrew:
+```sh
+brew install openapi-generator
+```
+Then to generate the java models from the open-api spec, you can run the
`generate-models` command.
+
+```sh
+make generate-models
+```
+If you would to remove the generated models, you can run the `clean-models`
command:
+```sh
+make clean-models
+```
