+## Dependencies
+
+To remotely Deploy Nix-Servers with Native Tools, you will need Access to the nixos-rebuild command.
+
+You can either use a NixOS System.
+
+Or you can Install the [Nix Package Manager](https://nixos.org/download/) and open a Nix-Shell with the Command available:
+
+``` bash
+nix-shell -p '(nixos{}).nixos-rebuild'
+```
+
+## Updating Configuration
+
+So, you updated the Configuration on your Computer, how can you apply the Updated Config to the Server?
+
+You'll need SSH-Access to the Server, with a User which can run Nix-Commands, and can escalate Privileges using sudo.
+
+1. Don't forget to Configure your ssh Config! (See [Hosts](#hosts))
+2. Stage the Changes if you created or deleted Files `git add .` (They will be ignored if you miss this step!)
+3. Build and Switch the Config on the Target Server! (Example [mow0m](#mow0m)
+
+``` bash
+nixos-rebuild switch --flake .#mow0m --target-host master@mow0m --build-host master@mow0m --use-remote-sudo 
+```
+
+You want to keep the Build-Host the Same as the Target-Host, because the Target will only accept Binarys with a trusted Signature. It is way easier, to just run the Build on the Same Machine then.
