 No matter the local installation approach you adopt, Composer is required.
 
-### Composer installation
+### Composer
 
 Drupal's Core, modules and themes, are all "packages" and Composer manages these dependencies in a structured and 
 organised manner. To put a Drupal website together, all assets have to be sourced from a dedicated URL and compiled to 
 create a fully functional build. To do that, Composer i.e. Drupal's dependency manager of choice, has to be present on 
 your local system.
 
 There are two ways to install Composer, locally and globally. The latter is usually preferred as, with a single 
-executable installed once, it allows Composer to manage the dependencies of multiple projects present on your machine. 
-To install Composer, follow the detailed instructions on the 
-[official Composer documentation page](https://getcomposer.org/doc/00-intro.md#globally).

 ### Working with Lando/DDEV containerized servers
 
 Many of us use a containerization technology locally for testing and development, such as Lando or DDEV. Both of these
-tools simplify the process of setting up and managing development environments for web projects. To use LGD locally with 
-either Lando or DDEV, you'll need to have Docker Desktop installed first.
