Looking for a doc about Ionic components used in PWA Toolkit

Hi everybody,

Does someone knows where can I found a doc about Ionic components which are used in Ionic PWA Toolkit ?

I just start an experimental app using Stenciljs and Ionic PWA Toolkit with Josh Monory tutorial (https://www.joshmorony.com/building-a-pwa-with-stencil-an-introduction-to-stencil/) and I see than Ionic components doesn’t exactly works like in ionic-angular.

For exemple, in Ionic we use :

<ion-buttons end> ... </ion-buttons>

and in Stenciljs we use :

<ion-buttons slot="end"> ... </ion-buttons>

and my problem is that I don’t know where can I found any doc which explain, for example, that in Stenciljs “if you want to specify ion-buttons position, you need to put “slot” attribute where the attribute’s value is the position”

Thanks
