 Installs [Nix](https://nixos.org/nix/) on GitHub Actions for the supported platforms: Linux and macOS.
 
 By default it has no nixpkgs configured, you have to set `nix_path`

 # Features
 
 - Quick installation (~4s on Linux, ~20s on macOS)

+- [Self-hosted GitHub runner](https://docs.github.com/en/actions/hosting-your-own-runners/about-self-hosted-runners) support

-- Allows specifying extra Nix configration options via `extra_nix_config`
+- Allows specifying extra Nix configuration options via `extra_nix_config`
 - Allows specifying `$NIX_PATH` and channels via `nix_path`
 - Share `/nix/store` between builds using [cachix-action](https://github.com/cachix/cachix-action) for simple binary cache setup to speed up your builds and share binaries with your team
-- Enables `flakes` and `nix-command` experimental features by default (to disable, set ``experimental-features`` via ``extra_nix_config``)

-## Hacking
+### How do I pass environment variables to commands run with `nix develop` or `nix shell`?
 
-Install the dependencies
+Nix runs commands in a restricted environment by default, called `pure mode`.
-```bash
+In pure mode, environment variables are not passed through to improve the reproducibility of the shell.
-$ yarn install
+
+You can use the `--keep / -k` flag to keep certain environment variables:
+
+```yaml
+- name: Run a command with nix develop
+  run: nix develop --ignore-environment --keep MY_ENV_VAR --command echo $MY_ENV_VAR
+  env:
+    MY_ENV_VAR: "hello world"
 ```
 
-Build the typescript
+Or you can disable pure mode entirely with the `--impure` flag:
-```bash
-$ yarn build
-```
 
-Run the tests :heavy_check_mark:
+```
-```bash
+nix develop --impure
-$ yarn test
 ```
