+Requirements
+============
+
+GNUnet's directed acyclic graph (DAG) will require around 0.74 GiB
+Diskspace, with GNUNet itself taking around 9.2 MiB reported by the
+build on GNU Guix.
 
 How to install?
 ===============
 
-The fastest way is to use a binary package if it is available for your
-system.  For a more detailed description, read the installation
-instructions on the webpage at https://gnunet.org/installation.
+
+binary packages
+~~~~~~~~~~~~~~~
+
+We recommend to use binary packages provided by your Operating System's
+package manager. GNUnet is reportedly available for at least:
+
+Gentoo (via the 'youbroketheinternet' overlay), GNU Guix, Nix,
+Debian, ALT Linux, Archlinux, Deepin, Devuan, Hyperbola, Kali Linux,
+LEDE/OpenWRT, Manjaro, Parabola, Pardus, Parrot, PureOS, Raspbian,
+Rosa, Trisquel, and Ubuntu.
+
+If GNUnet is available for your Operating System and it is missing,
+send us feedback so that we can add it to this list. Furthermore, if
+you are interested in packaging GNUnet for your Operating System,
+get in touch with us at address@hidden if you require
+help with this job.
+
+If you were using an Operating System with the apt package manager,
+GNUnet could be installed as simple as:
+
+$ apt-get install gnunet
+
 Generic installation instructions are in the INSTALL file in this
 directory.
 
+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.
+
+
+Some Operating Systems currently require you to build GNUnet from
+source.
+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 your Operating System
+simply lacks support for a binary package at the moment.
+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.
