 You can use these scripts to start replay at system startup if you add `scripts/start-replay.sh` to startup (this can be done differently depending on your desktop environment / window manager) and then go into
 hotkey settings on your system and choose a hotkey to run the script `scripts/save-replay.sh`. Modify `scripts/start-replay.sh` if you want to use other replay options.
 ## Run replay on system startup
-If you are running a distro that uses systemd then you can use the systemd service in `extra/gpu-screen-recorder.service`.
-Copy `extra/gpu-screen-recorder.service` to a location where systemd can find it, for example: `$HOME/.config/systemd/user` and then enable and start it with: `systemctl enable --now --user gpu-screen-recorder`. Copying the systemd service file is not needed if you installed GPU Screen Recorder from AUR as this is done automatically.
-You can then use the `scripts/save-replay.sh` script to save a replay. The systemd service is configured with the file `$HOME/.config/gpu-screen-recorder.env` (create it if it doesn't exist).
-You can see which variables that you can use by looking at the gpu-screen-recorder.service file. In general you only need to set the `WINDOW` variable to make it work.
-Restart the systemd service after modifying that configuration file. By default it saves videos in `$HOME/Videos`.\

 If you are using a NVIDIA GPU then it's recommended to set PreserveVideoMemoryAllocations=1 as mentioned in the section below.

 ## Issues
 ### NVIDIA
 Nvidia drivers have an issue where CUDA breaks if CUDA is running when suspend/hibernation happens, and it remains broken until you reload the nvidia driver. To fix this, either disable suspend or tell the NVIDIA driver to preserve video memory on suspend/hibernate by using the `NVreg_PreserveVideoMemoryAllocations=1` option. You can run `sudo extra/install_preserve_video_memory.sh` to automatically add that option to your system.
