 If you are loading up a client outside of vanilla Minecraft or Forge (Optifine and for an example), you'll need to download the needed files yourself if you don't provide downloads url downloads like Forge and Fabric. If no version jar is specified, MCLC will default back to the normal MC jar so mods like Fabric work.
 ##### Installer
 This runs an executable with specified launch arguments. Was used to support Forge 1.13 before ForgeWrapper.
+##### Authentication
+MCLC's authenticator module does not support Microsoft authentication. You will need to use a library like [MSMC](https://github.com/Hanro50/MSMC). If you weant to create your own solution, the following is the authorization JSON object format.
+```js
+{
+    access_token: '',
+    client_token: '',
+    uuid: '',
+    name: '',
+    user_properties: '{}',
+    meta: {
+        type: 'mojang' || 'msa',
+        demo: true || false
+        // properties only exists for specific Minecraft versions.
+        xuid: '',
+        clientId: ''
+    }
+}
+```
