+Hello, and welcome to Stormux!
+
+Let's get you set up. After you press enter, you will be prompted for the sudo password.
+When that happens, type the word stormux and press enter.
+You will not receive any speech feedback for this process.
+That is completely normal, and speech will return after you have typed the password.
+Once again, the password is stormux in all lower case letters.

+Please press enter to continue.
