Being based on Debian, AIMS Desktop uses the APT (Advanced Package Tool) to manage software.

Software and its dependencies on AIMS Desktop is managed via packages, for each program on
your computer, there is at least one package. Packages can be installed, removed or upgraded.

Here we will show you how to manage software using APT in the command line. APT needs root
(administrator) privileges, so you need to run it using the sudo command.

For example, if you want to install the program "meld", you would use `apt install`:

```
$ sudo apt install meld
```

If you would like to remove that package, you can use `apt remove`:

```
$ sudo apt remove meld
```

good way of doing this to the take the first letter of each word
and the grammar of a phrase you can remember.</span></li>

things.</span></li>
