-## Building with Autotools
-
-Older branches of Flatpak used GNU Autotools. See
-https://github.com/flatpak/flatpak/blob/flatpak-1.14.x/CONTRIBUTING.md
-for more details of that build system.
-
-The Autotools build system is likely to be removed from a future version
-of Flatpak, leaving Meson as the only build system supported.
-
-Newer releases of Flatpak do not include Autotools-generated files in
-the source archive. If it is necessary to build these releases with
-Autotools for some reason, the build system must be set up by running:
-
-    ./autogen.sh
-
-before proceeding as if for any other Autotools project.
