+## MySQL Client Tests
+We created smoke tests for Dolt's MySQL client integrations and we run these tests through Github Actions
+on pull requests.
+
+These tests can be run locally using Docker. From the root directory of this repo, run:
+```bash
+$ docker build -t mysql-client-tests -f MySQLDockerfile .
+$ docker run mysql-client-tests:latest
+```
+
+The `docker build` step will take a few minutes to complete as it needs to install all of the
+dependencies in the image.
+
+Running the built container will produce output like:
+```bash
+$ docker run mysql-client-tests:latest
