-## Installing upstream Nix
-
-Although Determinate Nix is the default, you can also use this Action to install [upstream Nix][upstream].
-Make sure to set `determinate: false` in the Action's configuration:
-
-```yaml
- uses: DeterminateSystems/nix-installer-action@main
-  with:
-    determinate: false
-```
-
-This option will be available until **January 1, 2026**, at which point installing upstream Nix using this Action will no longer be possible.
