 ### Debian Package(Ubuntu 23.04 dependencies)

+
+### NixOS/Home-manager
+
+ReSet offers a flake with a home-manager module which you can use to declaratively install ReSet and plugins.
+Here is an example configuration:
+
+```nix
+#inputs
+reset.url = "github:Xetibo/ReSet";
+reset-plugins.url = "github:Xetibo/ReSet-Plugins";
+
+#installation and configuration
+  programs.reset.enable = true;
+  programs.reset.config.plugins = [
+    inputs.reset-plugins.packages."x86_64-linux".monitor
+    inputs.reset-plugins.packages."x86_64-linux".keyboard
+  ];
+  programs.reset.config.plugin_config = {
+    #custom toml config
+    Keyboard = {
+      path = "/home/user/.config/reset/keyboard.conf";
+    };
+  };
+```
+
 ### crates
+
 ```
 cargo install reset
 ```
+
 ### Compiled Binary
 
 The compiled binary is provided in the releases.
 
 ## Usage
+
 Besides starting the application itself, a standalone daemon version ([ReSet-Daemon](https://github.com/Xetibo/ReSet-Daemon)) also exists, which is what provides the functionality for ReSet.\
 It is therefore possible to use a different application as well for interacting with the daemon.
 
 By default, the daemon is integrated into ReSet and is started automatically if no other daemon is found.
+
 ## Roadmap
 
 This application was developed as a semester project for the Eastern Switzerland University of Applied Sciences.
