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

-- Allows specifying extra Nix configuration options via `extra_nix_config`
+- Allows specifying extra Nix configration 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`)

-### How do I pass environment variables to commands run with `nix develop` or `nix shell`?
+## Hacking
 
-Nix runs commands in a restricted environment by default, called `pure mode`.
+Install the dependencies
-In pure mode, environment variables are not passed through to improve the reproducibility of the shell.
+```bash
-
+$ 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"
 ```
 
-Or you can disable pure mode entirely with the `--impure` flag:
+Build the typescript
+```bash
+$ yarn build
+```
 
-```
+Run the tests :heavy_check_mark:
-nix develop --impure
+```bash
+$ yarn test
 ```
