You need to at lest specify the gitSource query parameter!
		
		Supported query parameters are:
		
		gitSource - git URI from where to clone your content
		gitBranch - git branch that contains your rendered pages as html files (often gh-pages)
		namespace - the target namespace of goroom
		
		

Example query:
http://goroom.blum.coffee/ocp?gitSource=https://github.com/red-hat-storage/ocs-training.git&gitBranch=gh-pages&namespace=default
