This page allows you to download SàT and its related projects source code. There is not (yet) an installer to double click to make it work out of the box.
We are thinking about a way to allow everybody to easily install SàT at home, but for now it will seem difficult to the persons who are not familiar with GNU/Linux operating systems. For the Windows and MacOS users, the best way to test SàT for now is to visit our demonstration website running Libervia.
When not trivial (e.g. sat_media just needs to be extracted somewhere), the installation procedure is described in the INSTALL file that you will find in the package.
You are also welcome in our multi-user chat room: firstname.lastname@example.org.
To ease the procedure, you can also install the last SàT packages from PyPI, the Python Package Index.
Thanks to the maintainers of SàT packages, you might even find some really-easy-to-install packages in your distribution repositories!
But after all... the easiest is probably to run the Docker images :-)
