How do I add a C++ class from files I have?

I have a .h and .cpp file for a few of my classes. How to I get them so they show up in the editor?

Hello!

We talking about ue4 classes right? or what kind of classes?
Normally if you copy those files to Source directory (and i assume you have c++ based project)
then right click on project file, generate visual studio solution then compile… new classes will appaer and ready to use after you succesfully compiled…

But some picture / screenshot or code would be good to help on this…

Cheers
