Van first you run crontab -e
which opens a text editor with the current contents of your crontab (ie the schedule for your cron jobs).
Once the editor is open then you add the two lines:
# update awstats at 0500 UTC daily
0 5 * * * ~/apps/appname/awstats_cron
The format is indeed 0 space 5 space asterisk space asterisk space asterisk space ~/apps/appname/awstats_cron
.
Once you've entered those two lines, save and exit the editor and step 8 will be complete.
