composer.phar installModules are used for the collection of various information. There are two ways to implement modules:
Modules implementing the PeriodiclyUpdatedModuleInterface will collect and return information in fixed intervals. For example, this is used to display the current time, battery usage, sound volume or memory usage.
For example implementations of this, see the Module\Battery.php, Module\Sound.php or Module\Time.php.
