 To get the best experience, use a GIF viewer that can handle animated gifs.
 On OS X you can use Safari using "open -a Safari smily.gif"

 least 2MiB of memory to run in.
 
 ## Author's comments:
+
 This program generates an animated GIF from a plain text.  Run:
 
-    gcc -o prog prog.c
-    ./prog < invisible.txt > invisible.gif
+```sh
+cc -o prog prog.c
+./prog < invisible.txt > invisible.gif
+```
 
 Open invisible.gif and then wait a minute.  You will see a hidden message.
 Can you tell the difference between letters that leaves the mark and ones that does not?
 
 Other examples:
 
-    ./prog < golem.txt > golem.gif
-    ./prog < smily.txt > smily.gif
+```sh
+./prog < golem.txt > golem.gif
+./prog < smily.txt > smily.gif
+```
 
 The program itself has a hidden message.
 
-    ./prog < prog.c > prog.gif
+```sh
+./prog < prog.c > prog.gif
+```
