+### Authentication
+
+TODO (incomplete, experimental), see [https://github.com/deathcap/wsmc/issues/2](https://github.com/deathcap/wsmc/issues/2).
+First login through the regular Minecraft client, with your account, and you'll get a per-user URL to login to WSMC
+(can be disabled with `announce-on-join: false`). Alternatively the same URL can be retrieved using the `/web` command,
+either from a player or with `/web playername` from the server console.
+
+Authentication can be disabled by setting `allow-anonymous: true` (for testing purposes, warning: allows logging in as any user).
+
+#### Command-line mode
+
+Alternatively, the plugin can be used from the command-line, for testing purposes (no auth):
+
+    java -cp target/wsmc*.jar deathcap.wsmc.Main 0.0.0.0 24444 localhost 25565
