## Troubleshooting
### My shell has changed
There 2 possible solutions:
First, using [direnv](https://direnv.net/) to manage your dev environments. See [direnv-guide](https://haskell.flake.page/direnv). This is the recommended approach.
Second is a simple-unreliable hack, which is adding a `shellHook` to `devShells`
```nix
devShells.default = pkgs.mkShell {
shellHook = ''
exec $SHELL
'';
};
```
You might get a lot different issues, use it at your own risk.
