 You may use Composer to install Pint into your PHP project:
 
-    composer require laravel/pint --dev

 ## Running Pint
 
 When running Pint, it will output a list of files that have been fixed. It is possible to see the changes made in more detail using the `-v` option:
 
-    ./vendor/bin/pint -v
+```bash
+./vendor/bin/pint -v
+```
 
 In addition, if you would like Pint to simply inspect your code for style errors without actually changing the files, you may use the `--test` option:
 
-    ./vendor/bin/pint --test
+```bash
+./vendor/bin/pint --test
