+Before getting into all the details of the `alv` language, let's quickly run an
+example program to make sure that everything is working correctly:
+
+    ([1]import* time)
+    ([2]print ([3]every 0.5 "hello world!"))
+
+Open a text file save this piece of code as `hello.alv`. You can also find this
+example program in the repository and the windows binary package.
+
+As mentioned earlier, there are two different ways to run `alv` programs: using
+the copilot GUI, or in the terminal.
+
+## starting the copilot GUI
+On Linux and Mac OS X, you can launch the GUI by executing the `alv-fltk`
+command. On Windows, you can double-click `alv-fltk.bat`. This window should
+open:

+
+Now open `hello.alv` using `File > Open Script` or the shortcut `^O`
+(control-O). The copilot should start printing `hello world` over and over
+again in the lower field.
+
+You can pause and resume execution using the `Run` button or the `^P` shortcut.
+To stop the program simply close the window.
+
+## starting the copilot in the terminal
+To run a file in the terminal, invoke the command `alv <path/to/hello.alv>`. If
+your system cannot find the `alv` command, check your installation and `PATH`.
+On Windows, it is also possible to drag your `alv` file onto `alv.bat`.
+
+You should now see the text `hello world` being printed over and over again,
+twice a second. You can stop the copilot by pressing `^C` (control-C).
