 Graphics/Game engine written in Vulkan. More of a science project than the actual engine that will be used anywhere.
 
+# Running
+There are couple of usefull scripts to build and run this project.
+
+## prepare_env.py
+[WIP] This python script will download all project dependencies that are present in dependencies.dep file. It can be
+either git repo link or an archive to be downloaded.
+
+## run.sh
+Sice we wan to use Vulkan version that is bind to this project, couple of environment variables need to be added to be
+able to run this project. run.sh script will set those variables and run the executable.
