+Scope of Operating System support
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+We actively support GNUnet on a broad range of Free Software Operating
+Systems.
+
+For proprietary Operating Systems, like for example Microsoft Windows
+or Apple OS X, we accept patches if they don't break anything for
+other Operating Systems.
+If you are implementing support for a proprietary Operating System,
+you should be aware that progress in our codebase could break
+functionality on your OS and cause unpredicted behavior we can
+not test. However, we do not break support on Operating Systems
+with malicious intent.
+Regressions which do occur on these Operating Systems are 3rd
+class issues and we expect users and developers of these
+Operating Systems to send proposed patches to fix regressions.
+
+For more information about our stand on some of the motivating
+points here, read the 'Philosophy' Chapter of our handbook.
+
+Building GNUnet from source
+~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+IMPORTANT: You can read further notes about compilation from source in
+the 'doc/FILENAME' document, which includes notes about specific
+requirements for operating systems aswell. If you are a package
+mantainer for an Operating System we invite you to add your notes if
+you feel it is necessary and can not be covered in your Operating
+System's documentation.
+
+If you are building GNUnet from source you are either interested
+in furthering its development (we have further notes for developer
+builds in our 'GNUnet Developer Handbook') or you don't trust other
+people's binaries or your Operating System doesn't provide any
+binary package (at the moment).
+
+If you're on Gentoo you can build GNUnet using the recipes provided
+in the 'youbroketheinternet' overlay. Other Operating Systems may
+unintentionally require you to build GNUnet from source.
+
+Two prominent examples which currently lack cross-compilation
+support in GNUnet (and native binaries) are MS Windows and Apple macOS.
+For macOS we recommend you to do the build process via Homebrew and a
+recent XCode installation. We don't recommend using GNUnet with any
+recent MS Windows system as it officially spies on its users (according
+to its T&C), defying some of the purposes of GNUnet.
