Prosperity: Installing recommended plugins
We highly recommend to install Jetpack plugin which provides powerful features previously only available to WordPress.com users. Jetpack is developed by Automattic, the makers of WordPress.com.
After the plugin was installed and activated, you will be asked to connect to WordPress.com. If you don’t have a WordPress.com account, you can create one. It’s totally free and easy. Note, it does not force you to build a site on WordPress.com.
The reason you should connect to WordPress.com is because many of Jetpack modules are integrated with specific robust functionality of that platform.
Important: You do not need to pay for any plans when connecting to WordPress.com. Simply choose a free account in order to have the features shown on the demo site.
If you are working on a localhost then you will not be able to connect to WordPress.com. In this case, you can use a development mode in order to have the features that do not require a connection to WordPress.com servers.
