+This package allows you to create ephemeral MySQL databases from JavaScript and/or TypeScript code and also the CLI, great for testing, CI, and learning MySQL. When creating a new database, if the version selected is not installed on the system, the binary is downloaded from MySQL's CDN (cdn.mysql.com)
 
 You can run multiple MySQL databases with this package at the same time. Each database will use a random free port. The databases will automatically shutdown when the JS runtime process exits. A `stop()` method is also provided to stop each database instance.
