218 THE OFFICIAL RASPBERRY PI BEGINNER'S GUIDE
If the category you’ve chosen has lots of software packages available, it may take some
time for the Add/Remove Software tool to finish working through the list.Installing software
To select a package for installation, check the box next to it by clicking on it. You can install
more than one package at once: just keep clicking to add more packages. The icon next to the
package will change to an open box with a ‘+’ symbol, to confirm that it’s going to be installed.When you’re happy with your choices, click either the OK or Apply button; the only difference
is that OK will close the Add/Remove Software tool when your software is installed, while the
Apply button leaves it open. You’ll be asked to enter your password, to confirm your identity –
you wouldn’t want just anyone able to add or remove software from your Raspberry Pi, after all!
