This full feature is coming soon, but you can test it with sample data.

1. You need to install magento without sample data, via composer create project as specified here.
2. Login to admin and navigate to System and look for Web Setup Wizard under tools.
3. Navigate to Magento Marketplace and enter your authentication keys for magento.com as specified here.
4. If you navigate back to component manager and click sync(this step may take a while), "purchases" made in the marketplace will eventually show up here. This is still WIP.
5. For now, you can test it with sample data modules. Under New Purchases it should show number of new modules(for now 20 for the number of sample-data modules). If you click install below that, you should be able to see a list of sample-data modules that can be installed.
6. Select the modules you want to install and click the install button on the upper left side of the grid. Or install one component at a time.
7. There will be a dependency check(which takes a while), based on composer that checks newly required components. This step requires cron to be setup. Instructions here
8. Next, you can optionally create a backup, and then finally install component, which is done via the crons setup in previous step and composer.
