 ### 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.

 ## 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
