NOTE: This page only applies to the flake package. You can safely skip this if
you use the Nixpkgs package.
The Hyprland flake is not built by Hydra, so it is not cached in
[cache.nixos.org], like the rest of Nixpkgs.
Instead of requiring you to build Hyprland (and its dependencies, which may
include `mesa`, `ffmpeg`, etc), we provide a Cachix cache that you can add to
your Nix configuration.
The [Hyprland Cachix](https://app.cachix.org/cache/hyprland) exists to cache the
`hyprland` packages and any dependencies not found in [cache.nixos.org].
{{< hint >}}
In order for Nix to take advantage of the cache, it has to be enabled **before**
using the Hyprland flake package.

```nix
# configuration.nix
{
nix.settings = {
substituters = ["https://hyprland.cachix.org"];
trusted-public-keys = ["hyprland.cachix.org-1:a7pgxzMz7+chwVL3/pzj6jIBMioiJM7ypFP8PwtkuGc="];
};
}
```
{{< hint type=important >}}
Do **not** override Hyprland's `nixpkgs` input unless you know what you are
doing.
Doing so will make the cache useless, since you're building from a different
Nixpkgs commit.
