 # ViaProxyMultiLaunch
-Launch another jar file in combination with ViaProxy.
+Launch another jar file in combination with ViaProxy.\
+This helps if your server host only allows you to run a single jar file.\
+A spare port to bind ViaProxy/the server to is needed.
 
 ## Usage
-The server <b>has</b> to be in a separate folder because of file conflicts with ViaProxy.\
-To use this plugin you have to launch ViaProxy instead of the normal server jar file.\
-The server jar has to be added to the launch arguments of ViaProxy:
-`````shell
-    [ViaProxy launch] --serverjar server.jar
-`````
+### Installation
+Download the latest release from the [releases page](https://github.com/ViaVersionAddons/ViaProxyMultiLaunch/releases) and place it in the `plugins` folder of the ViaProxy server.
+
+### Configuration
+When starting ViaProxy with the plugin installed for the first time, the config file (`multilaunch.yml`) will be generated in the server folder.\
+It contains all the necessary settings to configure the plugin.
+
