 ## Installation
+
+### Installation on [Drupal Project](https://github.com/drupal-composer/drupal-project)
+
+- In root folder add dependencies to composer.json:
+
+        composer require drupal/netsmtp drupal/mailsystem
+
+- Go to `web/` folder and enable netsmtp module:
+
+        drush en netsmtp -y
+
+### Installation on standard drupal
+
 This module defines external non-drupal dependencies via composer.json, 
 so you can use a drupal module [composer_manager](https://www.drupal.org/project/composer_manager) to install dependencies.
 
 **Procedure**
 
-- Download this module, composer_manager, mailsystem modules to the `modules/contrib` dir or similar.
-- Enable composer_manager module && clear cache
-- Enable netsmtp module
+- Download this module, composer_manager, mailsystem modules to the `modules/contrib` dir or similar:
+
+        drush pmi netsmtp, composer_manager, mailsystem -y
+
+- Enable composer_manager module && run install script && clear cache:
+
+        drush en composer_manager -y && php PATH_TO_COMPOSER_MANAGER_MODULE/scripts/init.php && drush cr
+
+- Enable netsmtp & mailsystem modules:
+
+        drusn en netsmtp, mailsystem -y
