+# Discord provider for Laravel Socialite
+A provider for [Laravel Socialite][1] that allows authentication as a Discord user.
+_Authenticating as a bot is currently not supported._
+
+## Installation
+```
+composer require martinbean/socialite-discord-provider
+```
+
+## Usage
+The package registers a Socialite driver with the name of `discord`.
+
+Before using the driver, create an OAuth application in Discord’s developer portal:
+https://discord.com/developers/applications
+
+Set your client ID and client secret as environment variables, and then reference them in your **config/services.php** file.
+You will also need to add a redirect URL to your application.
+
+```php
+<?php
+
+// config/services.php
+
+return [
+
+    // Any other services
+
+    'discord' => [
+        'client_id' => env('DISCORD_CLIENT_ID'),
+        'client_secret' => env('DISCORD_CLIENT_SECRET'),
+        'redirect' => '/auth/discord/callback',
+    ],
+
+];
+```
+
+The `redirect` value will need to match a redirect URL in your Discord application settings. It can be relative as above.
+
+Then, create a controller to redirect and handle the token callback:
+
+```php
+<?php
+
+namespace App\Http\Controllers\Auth;
+
+use App\Http\Controllers\Controller;
+use Laravel\Socialite\Facades\Socialite;
+
+class DiscordController extends Controller
+{
+    /**
+     * Redirect the user to the Discord authentication page.
+     *
+     * @return \Illuminate\Http\Response
+     */
+    public function redirectToProvider()
+    {
+        return Socialite::driver('discord')->redirect();
+    }
+
+    /**
+     * Obtain the user information from Discord.
+     *
+     * @return \Illuminate\Http\Response
+     */
+    public function handleProviderCallback()
+    {
+        $user = Socialite::driver('discord')->user();
+
+        // $user->token;
+    }
+}
+```
+
+### Scopes
+Discord supports various scopes. You can find a list here: https://discord.com/developers/docs/topics/oauth2#shared-resources-oauth2-scopes
+To request additional scopes when authenticating, you can use the `scopes` method before redirecting:
+
+```php
+return Socialite::driver('discord')
+    ->scopes(['guilds', 'messages.read'])
+    ->redirect();
+```
+
