If you open [D Library 
Reference](https://dlang.org/phobos/index.html) you are bound to 
see the **Internal API** section in the table of content.

What is the **Internal API** (internal.core, dmd, rt) for and 
when, how and where to use it?

They're modules that are supposed to be internal to the implementation. They
should not be accessible to anyone outside of those projects. So, it's
pretty weird that it's up on the website, but my guess is that someone put
it there so that the folks working on the code base could see the rendered
ddoc comments for that code. For instance, I could believe that the dmd
section there is there just to make it easier for some of the folks working
on the compiler to more easily get an overview of the public symbols within
those modules. But if you're not contributing to those projects, there
really isn't any reason to see those modules.
