-GStreamer [meson](http://mesonbuild.com/) based repositories aggregrator.
+This is GStreamer, a framework for streaming media.
 
-Check out this module and run meson on it, and it will git clone the other
-GStreamer modules as [meson subprojects](http://mesonbuild.com/Subprojects.html)
-and build everything in one go. Once that is done you can switch into an
-development environment which allows you to easily develop and test the latest
-version of GStreamer without the need to install anything or touch an existing
-GStreamer system installation.

-## Checkout another branch using worktrees

-If you need to have several versions of GStreamer coexisting (eg. `master` and `1.16`),
