-3. Install and run the [CloudSQL Proxy](https://cloud.google.com/sql/docs/mysql-connect-proxy)

-        $ mysql -h 127.0.0.1 -u root -p -e "CREATE DATABASE ;"
+To run locally, you can either run your own MySQL server locally and set the connection string in `app.yaml`, or you can [connect to your CloudSQL instance externally](https://cloud.google.com/sql/docs/external#appaccess).
