 ## Installation
 
 First, make sure Composer is installed correctly:
-```
-which composer
-```
+
+    which composer
 
 If you get composer not found or similar, follow Composer's installation
 instructions.
 
 Install Coder (8.x-2.x) in your global Composer directory in your home directory
-(~/.composer):
-```
-composer global require drupal/coder
-```
+(`~/.composer`):
+
+    composer global require drupal/coder
+
+To make the `phpcs` and `phpcbf` commands available globally, add the Composer
+bin path to your `$PATH` variable in `~/.profile`, `~/.bashrc` or `~/.zshrc`:
 
-To make the phpcs and phpcbf commands available globally, add the composer bin path
-to your $PATH variable in ~/.profile, ~/.bashrc or ~/.zshrc:
-```
-export PATH="$PATH:$HOME/.composer/vendor/bin"
-```
+    export PATH="$PATH:$HOME/.composer/vendor/bin"
 
 Register the Drupal and DrupalPractice Standard with PHPCS:
-```
-phpcs --config-set installed_paths ~/.composer/vendor/drupal/coder/coder_sniffer
-```
+
+    phpcs --config-set installed_paths ~/.composer/vendor/drupal/coder/coder_sniffer
+
+
+### Composer Installer Plugins
+
+The Coder package (>= 8.2.11) now works with Composer Installer Plugins,
+that find and register standards whenever packages are installed or updated.
+To use such a plugin within your project, follow these steps.
+
+    composer require --dev dealerdirect/phpcodesniffer-composer-installer
+    composer require --dev drupal/coder
+
+Now, you will see Drupal and DrupalPractice listed in the available PHP
+CodeSniffer standards.
+
+    vendor/bin/phpcs -i
+
+The same can be done for a Composer global installation.
+
+    composer global require dealerdirect/phpcodesniffer-composer-installer
+    composer global require drupal/coder
 
 
 ## Usage
 
 Check Drupal coding standards
-```
-phpcs --standard=Drupal /file/to/drupal/example_module
-```
+
+    phpcs --standard=Drupal /file/to/drupal/example_module
 
 Check Drupal best practices
-```
-phpcs --standard=DrupalPractice /file/to/drupal/example_module
-```
+
+    phpcs --standard=DrupalPractice /file/to/drupal/example_module
 
 Automatically fix coding standards
-```
-phpcbf --standard=Drupal /file/to/drupal/example_module
-```
+
+    phpcbf --standard=Drupal /file/to/drupal/example_module

 ## Automated Testing (PHPUnit + PHPCS)
 
 Coder Sniffer comes with a PHPUnit test suite to make sure the sniffs work correctly.
 Use Composer to install the dependencies:
 
-```
-composer install
-```
+    composer install
 
 Then execute the tests:
-```
-./vendor/bin/phpunit
-```
+
+    ./vendor/bin/phpunit
 
 Then execute the coding standards checker on Coder itself:
-```
-./vendor/bin/phpcs
-```
+
+    ./vendor/bin/phpcs
