Magento 2, How to setup locally pwa studio for testing purpose only and please describe the pwa steps.I have used xampp with php 7.2.19 version.
Currently Magento have launched pwa-studio, but there is a theme on which Magento is working currently name "Venia".
You may find the steps described by Magento itself on this link (https://magento-research.github.io/pwa-studio/venia-pwa-concept/setup/).
You can simply colne from the repo and get to work. Let us know in case if you face any issue to do so further.
@Edit: If using windows it is recommended to use docker.
