The "Main Page" of the doxygen generated API reference is currently
totally empty. Expand it with some introductory text along with links
to the developer's guide, application developer's guide and the
pipeline and IPA module writer's guides.

Provide an easy link to switch between the reduced public reference
pages and the more complete internal ones.

Changes in v3:

	- renamed file to mainpage.dox

Changes in v2:

	- Changed the first paragraph to be more about what the documentation is
	than isn't (Jacopo)
	- Pushed the links to the guides into the \if internal block so that
	only the relevant one is presented.

+/**
+\mainpage libcamera API reference
+
+Welcome to the API reference for <a href="https://libcamera.org/">libcamera</a>,
+a complex camera support library for Linux, Android and ChromeOS. These pages
+are automatically generated from the libcamera source code and describe the API
+in detail - if this is your first interaction with libcamera then you may find
+it useful to visit the [developer's guide](../html/guides/introduction.html) in
+the first instance, which can provide a more generic introduction to the
+library's concepts.
+
+\if internal
+
+As a follow-on to the developer's guide, to assist you in adding support for
+your platform the [pipeline handler writer's guide](../html/guides/pipeline-handler.html)
+and the [ipa module writer's guide](../html/guides/ipa.html) should be helpful.
+
+The full libcamera API is documented here. If you wish to see only the public
+part of the API you can use [these pages](../api-html/index.html) instead.
+
+\else
+
+As a follow-on to the developer's guide, to assist you in using libcamera within
+your project the [application developer's guide](../html/guides/application-developer.html)
+gives an overview on how to achieve that.
+
+Only the public part of the libcamera API is documented here; if you are a
+developer seeking to add support for your hardware to the library or make other
+improvements, you should switch to the internal API
+[reference pages](../internal-api-html/index.html) instead.
