 Include the laravel-omnipay package as a dependency in your `composer.json`:
 
-    "ignited/laravel-omnipay": "3.*"
+    composer require ignited/laravel-omnipay "3.*"
 
 **Note:** You don't need to include the `omnipay/common` in your composer.json - it is a requirement of the `laravel-omnipay` package.
 
 Omnipay recently went refactoring that made it so that each package is now a seperate repository. The `omnipay/common` package includes the core framework. You will then need to include each gateway as you require. For example:
 
-    "omnipay/eway": "*"
+    composer require omnipay/eway "3.*"
 
 Alternatively you can include every gateway by requring:
 
-    "omnipay/omnipay": "*"
+    composer require omnipay/omnipay "3.*"
