+===== Technical requirements =====
+Please install GroIMP before the start of the summer school so we can start right away with the presentations.
+If you encounter any issues with the installation of the requirements please reach out to us so we can help you. We are available the whole week through E-mail, or we can set up a online meeting.
+==== GroIMP ====
+Please make sure you have version 2.2 of GroIMP installed. You can find instructions for Windows, Mac and Linux on https://wiki.grogra.de/doku.php?id=user-manual:ch01#requirements.
+Please make sure that everything works by following the steps shown here: https://wiki.grogra.de/doku.php?id=user-manual:ch01#testing_groimp_for_the_first_time.
+Note: This version requires Java 21. Make sure you have it installed.
+==== OpenGL/OpenCL ====
+Some features of GroIMP, most importantly the full spectral ray tracer (GPUFlux), require access to a Graphics Card and OpenCL.
+To test if GroIMP can access OpenCL, please go to the GroIMP main Menu on “Help/System Info.”
+Under Libraries OpenCL you can see if your library is loaded, in some cases, you have to scroll to the right to see the actual text.
+If GroIMP can not find a native OpenCL library and your computer has a graphics card, please install the OpenCL version provided by your Graphics card maintainer.
+If you do not have a graphics card or cannot install the drivers you can try to install POCL(https://portablecl.org/) which works like a “fake graphics card”, simulated on your CPU.
