+==== I receive a note about WebGL2. Why is that? ====
+If WebGL2 is not available, this message appears:
+//The configurator cannot be displayed without WebGL2 support. Please update the graphics card drivers and try again. You can find details about your device on [[https://webglreport.com/?v=2|WebGL2 report]]//
+WebGL 2 support may be deactivated when using a Firefox browser. Therefore, check this in Firefox:
+  - Enter ''about:config'' in the URL line
+  - Confirm that you want to edit the settings
+  - Filter for ''webgl2''
+  - Set the value ''webgl.enable-webgl2'' to ''true'' set
+{{pasted:20240527-084451.png}}
+Also check the value ''webgl.disabled''. Here is ''false'' is the correct value.
+The technology required to display the 3D scenes is WebGL2. This is supported from the following browser versions:
+  * Chrome from version 56
+  * Firefox from version 51
+  * Safari from version 15
+  * Edge from version 79
+  * Meta Quest Browser from Quest 1
+For Android devices, at least the following browser version must be available
+  * Chrome from version 124
+  * Firefox from version 125
+  * Samsung from version 7.2

+==== Instructions for use with a headset ====
+==== The product is no longer visible after the VR view with the headset? ====
+After leaving the VR view, you should reload the 3D view in the browser so that the position of the virtual viewer is updated.
+==== What do I do if the VR view does not fit my size? ====
+Calibrating the VR headset ensures correct size perception and ground position in the VR views. With the Meta Quest 3, repeatedly taking the VR headset off and on can lead to the feeling that the floor is too high. The feet then feel as if they are below the floor. This can be checked by placing the hand controller on the real floor. The virtual hand controller visible in the VR view must then also be on or above the floor. If this is not the case and the controller is below the floor, the VR headset (or the Guardian) must be recalibrated.
