 These exercises are tested on the [purgatorio](http://code.9front.org/hg/purgatorio/) fork of the Inferno operating system.
 
+The `;` rune in examples indicates a command to be run from the Inferno sh(1) shell. 
+
+## Building
+
+If a given example provides a mkfile:
+
+	; mk
+
+Otherwise, there will only be one file, a Limbo source file which can be built with:
+
+	; limbo file.b
+
+You could then run said file with:
+
+	; file
