 # Running the project
 
-We provide a simple script in ```bin/corfuHelloWorld.sh``` which will deal with the classpath automatically.
+We provide a simple script in ```bin/airline``` which will deal with the classpath automatically.
 The project uses the docopt command line parser for, simple readable command line options.
 
 To get help on options, simply type from the project directory:
 ```
-bin/corfuHelloWorld.sh --help
+bin/airline --help
 ```
 
-To run the project, type:
-```
-bin/corfuHelloWorld.sh run
-```
+## Make certain that the Corfu server is running
+
+This example assumes that both the Corfu server and Corfu client are
+running on the same machine.  If they run on different machines, use
+the `-c server-host:port-number` syntax on the client command line to
+specify where the server is located.
+
+To run the server to listen on TCP port 9000 (the default port), use:
+
+    /path/to/your/corfu-source-top-directory/bin/corfu_server -s -m 9000
+
+* `-s` = This will run the Corfu server in "single server" mode.
+* `-m` = The server will be running in "in-memory" mode (i.e., non-persistent)
+
+## Let's play with airplanes!
+
+If you just started the `corfu_server` process, then the database is
+empty.  When we view the database's contents, we won't see much.

+
+Excellent.  If we use the `./bin/airline view-database` command again,
+we'll see our two new airplanes now.

+
+We haven't added any flight schedules yet.  Let's do that.

+
+Note that the daily flight number, `FL 1`, has been assigned automatically
+by the system.  Let's add another flight with the same plane and with
+an overlapping time window.

+
+Oops.  We won't do that again.
 
+Let's add two more flights, then look at the flight schedule.
