-## NixOS
-To use NocoDB as a NixOS module, a flake.nix would be as follows:
-
-```
-{
-  description = "Bane's NixOS configuration";
-
-  inputs = {
-    nixpkgs.url = "github:nixos/nixpkgs/nixos-unstable";
-    nocodb.url = "github:nocodb/nocodb";
-  };
-
-  outputs = inputs@{ nixpkgs, nocodb, ... }: {
-    nixosConfigurations = {
-      hostname = nixpkgs.lib.nixosSystem {
-        system = "x86_64-linux";
-        modules = [
-          ./configuration.nix
-          nocodb.nixosModules.nocodb
-
-          {
-            services.nocodb.enable = true;
-          }
-        ];
-      };
-    };
-  };
-}

 ## Auto-upstall
 Auto-upstall is a single command that sets up NocoDB on a server for production usage.
 Behind the scenes it auto-generates docker-compose for you.
