-# Installation
 
-ECA can use different modellers. The recommended BPMN.iO modeller is used in this Quick Start guide.
+# Installing the ECA module
 
-Download the ECA module and BPMN.iO modeller module:
+This document explains how to install the Events - Conditions - Actions (ECA)
+module and its required components on your Drupal site.
+The installation process includes both the core ECA module and a modeler, which
+provides the user interface for creating automation models.
 
-```
+## Prerequisites
+
+Before installing ECA, your Drupal site should be up and running with
+administrative access.
+You need to have Composer installed to manage the module dependencies.
+
+## Installing with Composer
+
+Use Composer to download the `eca` Drupal module and the recommended `BPMN.iO`
+modeler.
+The `BPMN.iO` modeler provides a visual interface for creating your automation models.
+
+```shell
 composer require drupal/eca drupal/bpmn_io
 ```
 
-Install the ECA and BPMN.iO module and their dependencies via the GUI at `/admin/modules` or with Drush:
+## Enabling the modules
 
-```
+After downloading the modules, you need to enable them in Drupal.
+You can do this through Drupal's administrative interface or using `drush`.
+
+In Drupal, sign in as an administrator and go to the `Extend` page
+(`/admin/modules`).
+Find and enable the following modules: `ECA Core`, `ECA Base` and
+`BPMN.iO Modeller`.
+Select "Install" to complete the process.
+
+Alternatively, if you prefer using `drush`, you can enable the modules with this
+command:
+
+```shell
 drush -y pm:install eca eca_base bpmn_io
 ```
 
-The list of modules you may want to install depends on your use-case. You can now start building your own models.
+## Additional ECA sub-modules
+
+You might want to install additional ECA sub-modules.
+These sub-modules add support for extra events, conditions, and actions.
+
+ECA is also supported by a large number of Drupal contrib modules.
+Review the [extension guide](/eca/extend) and [plugin documentation](/plugins)
+to learn about available modules and how they can help you build more sophisticated
+automation models.
+
+## Next steps
+
+After completing the installation, you can begin exploring ECA's capabilities.
+Start by learning about [basic ECA concepts](/eca/concepts), read the
+[usage guide](/eca/usage), or explore the
+[library of example models](/library) for common use cases.
