docs: add high level page for the kernel community

We need documentation for the Linux kernel community to learn
about how to use KernelCI. So far we had nothing in that diretion
for the new architecture. This first version is quite simple,
but sets the foundation for expanding on this work.

+The Kernel Community is the audience of KernelCI. Upstream maintainers and developers, product makers, hardware vendors, etc. are all interested in getting the kernel tested on a variety of scenarios.
+
+> This documentation is still a **WIP**. As we ready new KernelCI for more users the documentation is being improved and expanded.
+
+This section of the documentation shares instructions to:
+* [enable kernel testing for your tree/branch](../api_pipeline/pipeline/developer-documentation/#enabling-a-new-kernel-tree)
+* [enable specific tests](../api_pipeline/pipeline/developer-documentation/#enabling-a-new-test)
+* visualize the results(TBD)
+
+We know that the documentation above may not answer all your questions. We are working to improve it. We ask you to reach out to our mailing list at [[email protected]](mailto:[email protected])  with questions and feedback. We are eager to hear from you!
