+# SteamVR
+
+The de facto standard for anything PCVR, SteamVR runs on Linux.
+
+Unfortunately the Linux version is riddled with bugs, missing features and bad performace, so in general it can be a subpar experience.
+
+You can use one of the alternatives listed in the [FOSS VR section](/docs/fossvr/).
+
+If you want to use a standalone headset with SteamVR you can check out [ALVR](/docs/steamvr/alvr/).
