 Aside from the default image, you may create your own by running the
 program as follows:

 To mitigate long runtimes, the program can be invoked in a "preview"
 mode by appending `-preview` to the command line arguments, like so:
 
-        ./zucker faster\! -preview > image.ppm
+```sh
+./zucker faster\! -preview > image.ppm

 If your platform distinguishes between binary and text streams, you
 may need to insert some code to reopen standard output in binary mode
 at the start of `main`. An ASCII platform is assumed.
