V uses apt. You can use it through the graphical PackageManager application (see below), or from a terminal:

sudo apt install <package>

To find a package by name or description, browse packages.v-os.dev or search from a terminal:

apt search <something>

To see what a package provides and what it depends on:

apt show <package>

The PackageManager application

PackageManager lists the packages in your apt sources, lets you filter them, shows each package’s details, and shows a summary of the changes before they are applied. An apt log view shows what apt did. It reads the same apt cache and sources as the commands above, so you can switch between the two.
