  ### Dependencies
  +These are the minimum dependencies required to build Alacritty, please note
  +that with some setups additional dependencies might be desired.
  +
  +If you're running Wayland with an Nvidia GPU, you'll likely want the EGL
  +drivers installed too (these are called `libegl1-mesa-dev` on Ubuntu).
  +
  #### Debian/Ubuntu
  You can build alacritty using `cargo deb` and use your system's package manager
