+Gaia Sky is a real-time, 3D, astronomy visualisation software free 
+and open source that provides a number of features that allows people 
+to observe and study the space in Virtual Reality. This slackbuild 
+install the prebuilt package released for Ubuntu.
+
+Gaia Sky is developed in the framework of ESA's Gaia mission to chart 
+about 1 billion stars of our Galaxy in the Gaia group of the 
+Astronomisches Rechen-Institut (ZAH, Universität Heidelberg). 
+
+Hardware requirements: CPU 4 core or higher, GPU with 1 GB RAM with 
+support for OpenGL (at least 3.2) and GLSL 3.3, memory with 2-6 GB RAM 
+depending on catalog, and at least 1 GB of free disk space depending 
+on datasets.
+
+*** WARNING ***
+1. Datasets
+Gaia Sky requires pre-packed datasets (Gaia eDR3, NBG, SDSS, OCDR2, 
+ecc.) provided by the project, but can be used with other datasets in 
+VOTable, FITS, CSV and other formats (STIL).
+When Gaia Sky starts for the first time, the application searches the 
+default dataset in ~/.local/share/gaiasky/data. If any dataset is not 
+found, Gaia Sky launches the Download Manager, a graphic interface 
+that allows to users to download the default dataset required. The 
+repository provides also other optional datasets which improve the 
+features of Gaia Sky (some datasets have very large size). For further 
+information, please read the README.SBo file.
+
+2. How to start Gaia Sky
+A Desktop entry which launches the GUI is provided with the 
+installation (in Education > Science), but Gaia Sky can be started by 
+command-line if you want apply some flags. About this mode please read 
+the README.SBo file.
+
+3. Virtual Reality
+The VR rendering is still in alpha mode: it is uncomplete and may 
+cause issues depending on the configuration.
