The Pi Store
The Pi Store is another tool that you can use to install software on your Raspberry Pi. The Raspberry Pi Store is installed by default in Raspbian and can be opened using the Pi Store icon on the desktop. The Pi Store groups together most of the best pieces of software that are available to be installed on your Raspberry Pi in one place.
The Pi Store is the only piece of software installed on your Raspberry Pi that actually sells commercial software and other content. To be able to purchase non-free software from the Pi Store, you need to register and provide a payment method such as a credit card.
The Pi Store is really easy to use:
Simply find the software that you want to install, and click on Buy Now.
Log in with your account, and away you go!
The Pi Store automatically handles all updates to any software that you have purchased.
