-## Installation Instructions
-Installation Instructions can be found **[in the wiki](https://git.nanody.de/anonoe/MMS/wiki/Installation-Instructions)**
+## MMS-client Installation
+#### 1. Install PrismLauncher
+PrismLauncher is a so-called 3rd-party-launcher, which makes installation and management of mods and modpacks very easy. Follow installation instructions on https://prismlauncher.org/
+#### 2. Log in with PrismLauncher
+On the top right "Accounts -> Manage Accounts... -> Add Microsoft". This opens the Microsoft website in your browser, where you have to login to your Microsoft account and then authorize PrismLauncher to access your "XBox account".  
+If your broser doesnt start automatically, copy the URL displayed and paste it into your browser.  
+This will allow PrismLauncher to generate a token, which grants temporary access to your XBox/Minecraft account. PrismLauncher stores this token only on your device and only uses it to launch Minecraft with your Minecraft account.
+#### 3. Import the modpack
+On the top left "Add Instance -> Import".  
+Paste the following link:  
+`https://git.nanody.de/api/packages/anonoe/generic/MMS-client/1.2/nanoMMS-modpack-client-v1.2.zip`  
+and press "OK".
+#### 4. Launch game and join server
+Select the instance and press "Launch". Have a little patience for the downloads to finish and the game to launch. Finally join the server, if you are whitelisted.
