 Make sure the right controller bindings are selected by going into your controller settings and selecting 
 the bindings called "Default Beat Saber Bindings – Action Bindings for Beat Saber". Follow the steps below to do so. Please note that you may encounter error messages when opening Controller Settings – this might happen the first time you open the window, but should no longer be an issue afterewards. If you are constantly getting an error message, please [open an issue](https://github.com/nicoco007/DynamicOpenVR/issues).
