 # Introduction to Modules
 
 In the context of Drupal, a module is a software package which provides functionality not offered through Drupal itself.
 At CERN, this could be integration with CDS (https://cds.cern.ch/) to host media or Indico (https://indico.cern.ch/) to import and display events.
 By default, all CERN websites include a collection of CERN-specific modules through the centrally managed CERN Drupal Distribution.
-In addition to official CERN modules developed and maintained by the Web Team, the distribution also includes a collection of carefully cuarated community contributed modules, ensuring that the most common use-cases are accommodated out-of-the-box.
-
-While we always recommend websites to stick with what is included in the CERN Drupal Distribution, it is possible to install any number of modules made available to the wider Drupal community via https://www.drupal.org/project/project_module if such functionality is absolutely necessary.
-Kindly note, however, that installing community contributed modules in this manner requires website owners to assume responsibility of continued compatibility and maintenance in the event that the project becomes incompatible or otherwise discontinued.
+In addition to official CERN modules developed and maintained by the Web Team, the distribution also includes a collection of carefully curated community contributed modules, ensuring that the most common use-cases are accommodated out-of-the-box.

 We differentiate between three types of modules:
 
 1. CERN-official modules;
 2. Community-contributed modules included in the CERN Drupal Distribution; and
-3. Community-contributed modules installed by the website owner.
 
 This section will cover **CERN-official modules only**.

 It you lock the version(s) of the module(s) in your custom `composer.json`, it is **your responsibility** to ensure these are updated as necessary for both compatibility and security reasons. Additionally, if you choose to include specific versions of modules otherwise included in the CERN Drupal Distribution, it is your responsibility to ensure continued compatibility with other centralised modules. We strongly recommend not overriding what is included centrally and not locking modules to a specific minor version.
