The child elements of the `<engines>` element specify versions of Apache Cordova-based frameworks that this plugin supports. The CLI aborts with a non-zero code for any plugin whose target project does not meet the engine's constraints. If no <engine> tags are specified, the CLI attempts to install into the specified cordova project directory blindly.
->NOTE: In **Cordova 6.1.0+**, the recommended place to specify platform, plugin, and CLI dependencies
->is in a plugin's `package.json`. See [specifying Cordova dependencies](../guide/hybrid/plugins/index.html#specifying-cordova-dependencies)
