 ==== Other Linux/Unix - Build from source
 
-To build from source, you need the following tools and dependencies:
+See the https://developers.yubico.com/yubioath-desktop/Building_from_Source.html[build documentation].
-
-
-- `g++`
-- `make`
-- Python 3
-- Qt 5 development tools, including `qmake`
-- Qt QML development tools
-
-With these installed, the build procedure is:
-
-    $ git clone --recurse-submodules https://github.com/Yubico/yubioath-desktop.git
-    $ cd yubioath-desktop
-    $ qmake && make
-
-From version 4.3.0 forward, you can also use the source tarball which now also
-bundles source dependencies:
-
-    $ wget https://developers.yubico.com/yubioath-desktop/Releases/yubioath-desktop-4.3.0.tar.gz{,.sig}
-    $ gpg --verify yubioath-desktop-4.3.0.tar.gz.sig
-    $ tar xf yubioath-desktop-4.3.0.tar.gz
-    $ cd yubioath-desktop-4.3.0
-    $ qmake && make
-
-The runtime dependencies are:
-
-* QML modules:
- ** https://github.com/thp/pyotherside[PyOtherSide]
- ** Qt Labs Settings
- ** Qt Quick Controls
- ** Qt Quick Dialogs
-* The https://developers.yubico.com/yubikey-manager/[YubiKey Manager] Python
-  library
-
-With these installed, you can just run the program:
-
-    $ ./yubioath-desktop
-
-
-==== Packaging
-
-The files you need to include in a distribution package are:
-
-- The `yubioath-desktop` binary
-- The icon `resources/icons/yubioath.png`, installed as `yubioath.png` somewhere
-  on the
-  https://standards.freedesktop.org/icon-theme-spec/icon-theme-spec-latest.html#directory_layout[Qt]
-  or
-  https://doc.qt.io/qt-5/appicon.html#setting-the-application-icon-on-common-linux-desktops[Freedesktop]
-  icons search path, for example as `/usr/share/pixmaps/yubioath.png`
-- (Optional) The Desktop Application descriptor
-  `resources/yubioath-desktop.desktop`
