-This screen recorder can be used for recording your desktop offline, for live streaming and for nvidia-like instant replay,
+This is a screen recorder that has minimal impact on system performance by recording a window using the GPU only,
+similar to shadowplay on windows. This is the fastest screen recording tool for Linux.

+This screen recorder can be used for recording your desktop offline, for live streaming and for nvidia shadowplay-like instant replay,
 where only the last few seconds are saved.

 ## Note
+This software works only on x11.\
 Recording a window doesn't work when using picom in glx mode. However it works in xrender mode or when recording the a monitor/screen (which uses NvFBC).\
-Does not work when using gtk client side decorations (such as on Pop OS). Either disable those (if possible), install gtk-nocsd or record the whole monitor/screen if you have NvFBC.\
-NvFBC doesn't work with PRIME, so if you are using PRIME then you can't record the monitor/screen, you have to record a single window.\
-
-All recording modes record in hevc (h265) in a mp4 format, except live streaming that records in h264 in a flv format.
+For screen capture to work with PRIME (laptops with a nvidia gpu), you must set the primary GPU to use your dedicated nvidia graphics card. You can do this by selecting "NVIDIA (Performance Mode) in nvidia settings:\

+and then rebooting your laptop.
