 ### Purpose of Hosts Files
 Hosts files will reroute unwanted traffic from ad farms, behavioral tracking firms and malware sites to a blackhole; routing to 0.0.0.0 (localhost; your PC) when a request is made to a URL on the blacklist.

 For those of us who want our browser to behave like a browser and not a GPS anklet, this list will prove useful by blocking a [plethora of tracking URLs](firefox-includes).  A few of which, some Firefox users have noticed seem to phone home even when the setting is toggled off in about:config.
 
 ### Custom filters
 You can easily append any domain you want to blacklist directly from your home directory.  Your custom preferences will be stored with each subsequent update - set it and forget it!
 
+### Whitelisting
+If the upstream list curators block a domain you want to see, add it to `~/autohosts/whitelist` and run `sudo autohosts`
+
+Be sure to add nothing other than the domain(s) you want to whitelist to this file!  I added 3 examples to the default whitelist file; you can regex it (TLD domain with no prefix or suffix, to whitelist subdomains, too: `example`) or supply a full TLD: `www.example.com`
