-## Installation with NixOS:
-To use this theme with NixOS you will have to enable [flakes](https://wiki.nixos.org/wiki/flakes). Before you do this, please inform yourself if you really want to, because flakes are still an unstable feature.
-First you will have to add grub2 to your `flake.nix` file as a new input.
-```nix
-# flake.nix
-{
-  description = "NixOS configuration";
-  inputs = {
-    nixpkgs.url = "github:nixos/nixpkgs/nixos-unstable";
-    # Add grub2 themes to your inputs ...
-    grub2-themes = {
-      url = "github:vinceliuice/grub2-themes";
-    };
-  };
-  outputs = inputs@{ nixpkgs,  grub2-themes, ... }: {
-    nixosConfigurations = {
-      my_host = nixpkgs.lib.nixosSystem {
-        system = "x86_64-linux";
-        specialArgs = { inherit inputs; };
-        # ... and then to your modules
-        modules = [
-          ./configuration.nix
-          grub2-themes.nixosModules.default
-        ];
-      };
-    };
-  };
-}
-```
-After that, you can configure the theme as shown below. In this example it is inside the `configuration.nix` file but it can be any file you choose.
-```nix
-# configuration.nix
-{ inputs, config, pkgs, lib, ... }:
-{
-  boot.loader.grub = { ... };
-  boot.loader.grub2-theme = {
-    enable = true;
-    theme = "stylish";
-    footer = true;
-    customResolution = "1600x900";  # Optional: Set a custom resolution
-  };
-}
-```
+ - Install Tela theme into /boot/grub/themes:
+   - `sudo ./install.sh -b -t tela`
+
+ - Uninstall Tela theme:
+   - `sudo ./install.sh -r -t tela`
 
 ## Issues / tweaks:
+
 ### Correcting display resolution:
+
  - On the grub screen, press `c` to enter the command line
  - Enter `vbeinfo` or `videoinfo` to check available resolutions
  - Open `/etc/default/grub`, and edit `GRUB_GFXMODE=[height]x[width]x32` to match your resolution
  - Finally, run `grub-mkconfig -o /boot/grub/grub.cfg` to update your grub config
 
 ### Setting a custom background:
+
  - Make sure you have `imagemagick` installed, or at least something that provides `convert`
  - Find the resolution of your display, and make sure your background matches the resolution
-   - 1920x1080 >> 1080p
-   - 2560x1080 >> ultrawide
-   - 2560x1440 >> 2k
-   - 3440x1440 >> ultrawide2k
-   - 3840x2160 >> 4k
+   - (1920x1080 -> --1080p, 2560x1080 -> --ultrawide, 2560x1440 -> --2k, 3440x1440 -> --ultrawide2k, 3840x2160 -> --4k)
  - Place your custom background inside the root of the project, and name it `background.jpg`
  - Run the installer like normal, but with -s `[YOUR_RESOLUTION]` and -t `[THEME]` and -i `[ICON]`
    - Make sure to replace `[YOUR_RESOLUTION]` with your resolution and `[THEME]` with the theme
- - Alternatively, use the `-c` option to set a custom resolution
