+### Lumen Install
+
+This pacakges is focused on Laravel development, but it can also be used in Lumen with some workarounds. Because Lumen works a little different, as it is like a barebone version of Laravel and the main configuration parameters are instead located in `bootstrap/app.php`, some arreglements must be made.
+
+#### Enabling Facades
+
+While Laravel IDE Helper can generate automatically default Facades for code hinting, Lumen doesn't comes with Facades activated. You must enable them under the `Create The Application` section, uncommenting this line:
+
+```php
+// $app->withFacades();
+```
+
+From there, you should be able to use the `create_alias()` function to add additional Facades into your code.
+
+#### Adding the Service Provider
+
+You can install Laravel IDE Helper in `app/Providers/AppServiceProvider.php`, and uncommenting this line that registers the App Service Providers so it can properly load.
+
+```php
+// $app->register(App\Providers\AppServiceProvider::class);
+```
+
+If you are not using that line, that is usually handy to manage gracefully multiple Laravel/Lumen installations, you will have to add this line of code under the `Register Service Providers` section of your `bootstrap/app.php`.
+
+```php
+if ($this->app->environment() !== 'production') {
+    $this->app->register(\Barryvdh\LaravelIdeHelper\IdeHelperServiceProvider::class);
+}
+```
+
+After that, Laravel IDE Helper should work correctly. During the generation process, the script may throw exceptions saying that some Classes doesn't exist or there are some undefined indexes. This is normal, as Lumen has some default packages stripped away, like Cookies, Storage and Session. If you plan to add these packages, you will have to add them manually and create additional 
+Facades if needed.
+
+#### Adding Additional Facades
+
+Currently Lumen IDE Helper doesn't take into account additional Facades created under `bootstrap/app.php` using `create_alias()`, so you need to create a `config/app.php` file and add your custom aliases under an `aliases` array again, like so:
+
+```php
+return [
+    'aliases' => [
+        'CustomAliasOne' => Example\Support\Facades\CustomAliasOne::class,
+        'CustomAliasTwo' => Example\Support\Facades\CustomAliasTwo::class,
+        //...
+    ]
+];
+```
+
+Afyer you run ```php artisan ide-helper:generate```, it's recommended (but not mandatory) to rename `config/app.php` to something else until you have to re-generate the docs or after passing to a production enviroment. Lumen 5.1+ will read this file for configuration parameters if it is present, and may overlap some configurations.
