 # blocklist
 blocklist-installer
+This will install a cron to run daily and pull lists from https://blocklist.de to block malicious IP addresses. Adding around ~20,000 or more IP addresses per day, all voluntarily and freely contributed through people with Fail2Ban accounts. If setting up Fail2Ban I suggest you help contribute to blocklist.de.
+Script is pretty self explanatory it prepares IPTables persistence, and the cron tab. Simply run as root and it will do the work for you. 
+Tested on Ubuntu 14.04LTS
