 === Configuring OpenSim ===
+===========================
 
 When OpenSim starts for the first time, you will be prompted with a
 series of questions that look something like:
 
 [09-17 03:54:40] DEFAULT REGION CONFIG: Simulator Name [OpenSim Test]:
 
-At each of these you must provide you own value or just hit enter to
-take the default (in this case "OpenSim Test").
+For all the options except simulator name, you can safely hit enter to accept
+the default if you want to connect using a client on the same machine or over
+your local network.
 
-YOUR SIM WILL NOT BE STARTED UNTIL YOU ANSWER ALL QUESTIONS
+You will then be asked "Do you wish to join an existing estate?".  If you're
+starting OpenSim for the first time then answer no (which is the default) and
+provide an estate name.
+
+Shortly afterwards, you will then be asked to enter an estate owner first name,
+last name, password and e-mail (which can be left blank).  Do not forget these
+details, since initially only this account will be able to manage your region
+in-world.  You can also use these details to perform your first login.
 
 Once you are presented with a prompt that looks like:
 
-  Region# :
+  Region (My region name) #
 
 You have successfully started OpenSim.
 
-Before you can log in you will need to create a user account if you didn't already create
-your user as the "Master Avatar" during the region configuration stage.  You can do
-this by running the "create user" command on the OpenSim console.  This will
-ask you a series of questions such as first name, last name and password.
+If you want to create another user account to login rather than the estate
+account, then type "craete user" on the OpenSim console and follow the prompts.
