Notes from the video:

Modules allow you to install specific versions of a application, a good example of this would be the PHP application. The PHP application is available in the modules stream with multiple versions and editions, this allows you to select and install the specific version that is required.

To list all the currently available modules:

# dnf module list 

To list information about a specific module:

# dnf module info –profile php

To install a module:

# dnf module install php

To remove the module: 

# dnf module remove php

Then to reset the module post removal (if you would like to install a different version): 

# dnf module reset php 

To install a specific version and edition:

# dnf module install php:7.3/minimal
