+====================
 
-This script will cleanup video files older than 15 days.
-
-You need to add it in the crontab
+This script searchs and deletes videos older than 15 days. (You can change this value if you configure the script)
+You have to run it manually or add it to crontab for running it autmatically.
+The camera might throw an error if you try to run "crontab -e":
+```sh
+          crontab -e
+          crontab: chdir(/var/spool/cron/crontabs): No such file or directory
+```
+If that's the case just create that dir manually and you can edit the crontab with "crontab -e"
+Example configuration of crontab (runs the script the 15th of each month):
+```sh
+# Edit this file to introduce tasks to be run by cron.
+#
+# Each task to run has to be defined through a single line
+# indicating with different fields when the task will be run
+# and what command to run for the task
+#
+# To define the time you can provide concrete values for
+# minute (m), hour (h), day of month (dom), month (mon),
+# and day of week (dow) or use '*' in these fields (for 'any').#
+# Notice that tasks will be started based on the cron's system
+# daemon's notion of time and timezones.
+#
+# Output of the crontab jobs (including errors) is sent through
+# email to the user the crontab file belongs to (unless redirected).
+#
+# For example, you can run a backup of all your user accounts
+# at 5 a.m every week with:
+# 0 5 * * 1 tar -zcf /var/backups/home.tgz /home/
+#
+# For more information see the manual pages of crontab(5) and cron(8)
+#
+# m h  dom mon dow   command
+0 0 15 * * /home/hd1/test/scripts/delete_old_videos.sh
