+
+## What this is
+
+UNLOZE Webclient lets anyone play Counter-Strike Source directly in a web
+browser, streamed from a server-hosted instance of the game. This is aimed
+at players who don't own CSS on Steam or don't want to install it locally.
+
+Only one visitor controls the game at a time (via a queue system); others
+can watch the live stream while waiting their turn.
