In order to integrate MotoPress Content Editor to your theme you should follow these steps:

1. download the library of TGM Plugin Activation from its developers website http://tgmpluginactivation.com/

2. put class-tgm-plugin-activation.php file to root folder of your theme and create /plugins folder where you should put motopress-content-editor.zip file.

3. go to edit functions.php file of your theme and add settings for TGM Activation class and hook them to the tgmpa_register action.

/**
 * Include the TGM_Plugin_Activation class.
 */
require_once dirname( __FILE__ ) . '/class-tgm-plugin-activation.php';
add_action( 'tgmpa_register', 'my_theme_register_mpce_plugins' );
/**
 * Register the required plugins for this theme.
 *
 * The variable passed to tgmpa_register_plugins() should be an array of plugin
 * arrays.
 *
 * This function is hooked into tgmpa_init, which is fired within the
 * TGM_Plugin_Activation class constructor.
