 It's different from [WMR Lighthouse](/docs/steamvr/wmr-lighthouse/)
 
 This doesn't use steamvr to re-map the head from some lighthouse tracking device.
-Instead it does this natively, so SteamVR is only necessary for the proprietary `steamvr_lh` driver.

 ## Setup:
 Setup your lighthouse system on SteamVR Windows. The Linux SteamVR version does not work well. On windows: Update everything, pair everything & setup your room boundaries.
 
 Linux setup:
-* install steam
+* install Steam
 * Download SteamVR on Steam (try non beta version first)
-* configurations from windows copied over

 * mount your windows drive (e.g. at `/mnt`)
-* `cp "/mnt/Program Files (x86)/Steam/config" ~/.steam/steam/ -r`

+### Linux only setup
+It may be possible to use SteamVR on Linux to setup your room boundries, pair and update everything. This is untested, but try at least.
+You may need playspace moving via Wlx to fine tune the floor if you don't have a Windows install.
