 ### Running this on Windows
 
-If you don't already, you might need to set the default shell to `bash`.
-
-```powershell
-npm config set script-shell "C:\\Program Files\\git\\bin\\bash.exe"
-```
-
-You can revert it later, if you have issues, by doing:
-
-```powershell
-npm config delete script-shell
-```
-
-In some cases, the `postinstall` script doesn't auto-run after `npm install`, in which case, you can run that manually:
-
-```sh
-npm run postinstall
-```
-
-That should bring your environment to a state ready for testing.

 To roll the docs in PowerShell, make sure you set the env variable correctly, i.e.:
 
 ```powershell
