+KDE Runtime Docker image based on Ubuntu 18.04
+
+The provided Dockerfile will install the KDE Runtime over the Ubuntu 18.04 base image.
+Also, the obtained Docker image will contain the clone of https://github.com/analogdevicesinc/scopy-flatpak the scopy-flatpak recipe repository which can be found at /home/docker/scopy-flatpak
+
+In order to build the Flatpak package for Scopy inside this Docker image, it needs to be run using "--privileged" (otherwise there is a lack of access to necessary utilities).
+
+We built Scopy Flatpak in this image, then saved the newly created image as alexandratr/scopy-flatpak-bionic:scopy on Dockerhub. However, a clean image (without the Scopy Flatpak build) can be found as alexandratr/scopy-flatpak-bionic:clean on Dockerhub.
+
+Running make inside the scopy-flatpak folder will build the Scopy.flatpak artifact. An example of how to do this is illustrated in the "build_appveyor_flatpak.sh" and "inside_flatpak_docker.sh" scripts (which deploys a Scopy.flatpak for each Appveyor nightly build).
