+## Live Patching EDID
+On Wayland systems using an NVIDIA GPU, some VR headset EDIDs may need to be patched to appear as non-desktop displays. This ensures that Monado can correctly initialize the headset. This can be achieved by installing and using [edid-json-tools](https://github.com/Joel-Valenciano/edid-json-tools).
+The patch must be applied once per system boot. After that, you can restart the headset or Monado as many times as you like until the next reboot.
+### Installation
+- ```git clone https://github.com/Joel-Valenciano/edid-json-tools```
+- ```cd edid-json-tools```
+- ```python3 -m pip install --editable .[CLI]```
+edid-json-tools should now be installed.
+### Usage
+- Launch the monado pimax branch.
+- As soon as the main display flash black (meaning the headset connected in desktop mode) run ```sudo patch_edid override -d -m 1 DP-1"``` ensuring to change the connector identifier if appropriate.
+- Wait for monado to crash and the headset to disconnect.
+- Launch monado again. The headset should now initialize without any issues.

 ## Monado
 Use monado from the branch `pimax` from the repository `https://gitlab.freedesktop.org/Coreforge/monado/`.
 Make sure to use the lighthouse driver `steamvr_lh`, other lighthouse drivers are currently not supported with the pimax driver.
