I'm coming in late on this thread, so apologies if this has already been
suggested.

Specifically, to get the proper syntax, you need to 'man 5 crontab'. 
For an every 5 minute job, the first thing that comes to mind is this:

00,05,10,15,20,25,30,35,40,45,50,55 * * * * <some command or script>

This *might* also work:

*/5 * * * * <command>

I haven't tested either of these, so no promises. :)
