+
+We ask you to not ignore the issue template. Fill it out as good and correct as
+possible. Issues that don't adhere to our request will be closed for ignoring
+the issue template. This is because analyzing a bug without a log file is harder
+than necessary. Low quality bug reports are noise.
+
+Please go back and chose the proper issue template. Opening issues with this
+template will be closed immediately.
