-## Install
-
-### GNU/Linux

-You can fetch the release of Matrique on Flathub. The link is at the beginning of this README.

-Alternatively, you can download the Flatpak nightly build bundle from ![Gitlab CI](https://gitlab.com/b0/matrique/-/jobs/artifacts/dev/raw/flatpak/matrique.flatpak?job=build-flatpak).
-
-Open the bundle using your preferred software center.

-There are no tested builds on Windows yet, but you can fetch the nightly builds from ![AppVeyor](https://ci.appveyor.com/api/projects/BlackHat/matrique/artifacts/matrique.zip).
