 The `compile` line just tells Bob that it's time to compile your code. It will run the compiler with all the options. This is helpful as you don't have to type out your long command to compile everything any time you make a change.
+
+If you need to use a library, you can add a line like this in your Bobfile:
+
+```
+library "(library)";
+```
+
+This will look in your system's default directory for libraries (usually `/usr/lib`). Specify a custom directory with
+
+```
+libdir "(libdir)";
+```
+
+If you need to include a directory, do it like this:
+
+```
+include "(include)";
+```
