How do I configure CRON on my website so twitter plugin will be activated


I just created Twitter App for my website but its not connecting, am getting the error: twitter account verification failed and:
Note: To make the system to post to Twitter automatically you need to configure CRON to run
wget --tries=1 --timeout=99999 -O twitter.txt script every few minutes.
Here is an example of the full CRON script in Unix format to run the twitter plug-in every 5 minutes:
*/5 * * * * wget --tries=1 --timeout=99999 -O twitter.txt

how do I solve this?
