-# Lix NixOS module
-
-See the [official installation guide][install-guide] for details on usage of
-release versions.
-
-[install-guide]: https://lix.systems/install/
-
-See the [beta guide][beta-guide] for a setup guide on how to use HEAD:
-
-[beta-guide]: https://wiki.lix.systems/link/1
-
-## What does this do?
-
-This is an overlay wrapped in a NixOS module that will replace CppNix with Lix
-in nixpkgs. This is useful so that `nixos-rebuild`, `nix-direnv` and similar
-will use Lix.
-
-Optionally, it can build Lix from source.
-
-## Versioning with Lix
-
-The version of this overlay should match the major Lix version, *and* if
-running HEAD, it should be the latest available version of the overlay.
-Changes breaking the overlay are shamelessly done on HEAD, and we expect people
-doing such changes to have prepared corresponding fix commits to make to the
-overlay immediately after submitting their changes. If your build randomly
-broke when updating HEAD, try updating your overlay.
-
-The version of Lix pinned in this flake's `flake.lock` is a version of Lix
-that is expected to work, however if running HEAD, it can be assumed to work
-with HEAD as well if both `lix-nixos-module` and `lix` are the latest version.
-
-## Common pitfalls
-
-Various flake frameworks such as flake-parts and snowfall (and possibly Colmena
-in the future if they do a similar optimization) manage overlays separately
-from NixOS, since they provide `pkgs` pre-imported to NixOS. This saves a
-couple of seconds of evaluation time and resources, but it means that the NixOS
-option `nixpkgs.overlays` **is completely ignored** on these frameworks.
-
-If you are using such a framework, add `overlays.default` to the overlays list
-for said framework.
-
-## Flake structure and usage
-
-The flake here has two inputs of note:
-- `nixpkgs`, *which is unused for most people*. It is purely used for `checks`
-  in developing `lix-nixos-module` itself.
-
-  The installation instructions make it `follows` to make `flake.lock` less
-  confusing, but it is nonetheless unused.
-- `lix`, which determines the version of Lix to do source builds for, if doing
-  source builds.
-
-These are the most relevant outputs for most people:
-
-- `nixosModules.lixFromNixpkgs` - uses Lix from nixpkgs and installs the
-  overlay to use Lix on a NixOS system. This is only useful for a stable
-  version of Lix, and cannot be used for running HEAD.
-- `nixosModules.default` - uses Lix from source and installs the overlay to use
-  Lix on a NixOS system.
-- `overlays.lixFromNixpkgs` - overlay to use Lix from nixpkgs in place of Nix.
-- `overlays.default` - overlay to use Lix from source in place of Nix.
-
-## Non-flake usage
-
-Import `module.nix` or `overlay.nix` as desired, with the arguments `lix`
-(derivation-like attribute set with the Lix sources, or `null` to use Lix from
-nixpkgs) and `versionSuffix` (optional string).
-
-It's desirable to also include a `versionSuffix` like the following while
-building HEAD from source, to have `nix --version` include date and commit
-information. To get such metadata, it depends on which pinning system is in
-use, but `builtins.fetchGit` will provide the necessary metadata for the
-following to work:
-
-```
-versionSuffix = "pre${builtins.substring 0 8 lix.lastModifiedDate}-${lix.shortRev or lix.dirtyShortRev}";
-```
