How to set env dev?

may we have a tuto that explain ionic setup env ?

The Ionic docs are great place to start - Open-Source UI Toolkit to Create Your Own Mobile or Desktop Apps

place to start OK
place to deploy not sure

I know that you encapsulate but sometime, you should propose deploy around Android and iOS or other if you want.

But sometime the question is : do i really need hybrid instead of direct access to platform.

Here is my frustration to found why ionic “bug”

thanks to all for your sharing knowledge
