Ionic3 documet redirect ionic4

When I searched ionic3 document for ionic3 component or api,
It redirect to ionic 4 document and the result not applicable to ionic 3.
It makes me very inconvenience.

You can check migration guide on

It is not solution for me.


If you are on ionic 4 documentation, then there is in upper right corner a small v3 button, that will lead you the v3 docs.
