Drupal is a great CMS (Content Management System), but everything isn't included in the core installation package of Drupal. Luckily there are thousands of modules (another word for plugin) made just for this easy way to build a website that fits your needs. When this screencast was recorded there were over 32000 modules available, and though it's just over two months since version 8 of Drupal was released there are already over 1000 modules for this version.
We continue our thorough journey alongside Drupal and explain two ways of adding modules and themes to your Drupal installation. Never install modules or themes from some place other than drupal.org. Other publishing systems have had and are having problems with plugins being available from here and there, and on more than one occasion there have been malicious code in these plugins.
I show you the two easiest ways as a newcomer to Drupal to add functionality via new modules and we touch subjects as Update Manager, security and security updates and the commenting module Disqus (which we use here on screencast.kodamera.se).
