### Examples:
- Install Tela theme on 2k display device:
```sh
sudo ./install.sh -t tela -s 2k
```
- Install Tela theme with custom resolution:
```sh
sudo ./install.sh -t tela -c 1600x900
```
- Install Tela theme into /boot/grub/themes:
```sh
sudo ./install.sh -b -t tela
```
- Uninstall Tela theme:
```sh
sudo ./install.sh -r -t tela
```
## 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";

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.

};
}
```
## 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

- 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
