+This examples directory shows some examples written in PowerShell.
+
+On Windows, note that each .ps1 file also requires a .cmd file to launch it.
+The WebSocket should connect to ws://..../[example].cmd.
+On Linux this is not required due to the shebang (#!/usr/bin/env pwsh).
+
+You can also test the command files by running from the command line.
