-# Raspberry Pi Ad Blocker 
-**A black hole for ads, hence Pi-hole**
-
-![Pi-hole](http://i.imgur.com/wd5ltCU.png)
-
-The Pi-hole is a DNS/Web server that will **block ads for any device on your network**.

-## Coverage
-Featured on [MakeUseOf](http://www.makeuseof.com/tag/adblock-everywhere-raspberry-pi-hole-way/) and [Lifehacker](http://lifehacker.com/turn-a-raspberry-pi-into-an-ad-blocker-with-a-single-co-1686093533)!

-## Automated Install
+# Automated Install 
+#### Designed For Raspberry Pi B, B+, 2,
+##### and Zero (with an Ethernet adapter)
 
 1. Install Raspbian 
-2. Set a **static** IP address
-3. Run the command below
+2. Run the command below
 
-```curl -s "https://raw.githubusercontent.com/jacobsalmela/pi-hole/master/automated%20install/basic-install.sh" | bash```
+### ```curl -L install.pi-hole.net | bash```
+
+![Pi-hole automated installation](http://i.imgur.com/Un7lBlj.png)
 
 Once installed, **configure any device to use the Raspberry Pi as its DNS server and the ads will be blocked**.  You can also configure your router's DHCP options to assign the Pi as clients DNS server so they do not need to do it manually.

+## Partnering With Optimal.com
+
+Pi-hole will be teaming up with [Rob Leathern's subscription service to avoid ads](https://medium.com/@robleathern/block-ads-on-all-home-devices-for-53-18-a5f1ec139693#.gj1xpgr5d).  This service is unique and will help content-creators and publishers [still make money from visitors who are using an ad ablocker](http://techcrunch.com/2015/12/17/the-new-optimal/).

+
+A more detailed explanation of the installation can be found [here](http://jacobsalmela.com/block-millions-ads-network-wide-with-a-raspberry-pi-hole-2-0).

 ## Gravity
-The [gravity.sh](https://github.com/jacobsalmela/pi-hole/blob/master/gravity.sh) does most of the magic.  The script pulls in ad domains from many sources and compiles them into a single list of [over 900,000 entries](http://jacobsalmela.com/block-millions-ads-network-wide-with-a-raspberry-pi-hole-2-0).
+The [gravity.sh](https://github.com/jacobsalmela/pi-hole/blob/master/gravity.sh) does most of the magic.  The script pulls in ad domains from many sources and compiles them into a single list of [over 1.6 million entries](http://jacobsalmela.com/block-millions-ads-network-wide-with-a-raspberry-pi-hole-2-0).
 
 ## Whitelist and blacklist
 You can add a `whitelist.txt` or `blacklist.txt` in `/etc/pihole/` and the script will apply those files automatically.
 
 ## Web Interface
-I am also working on a [Web interface](https://github.com/jacobsalmela/AdminLTE#pi-hole-admin-dashboard) so you can view stats and change settings.
+The [Web interface](https://github.com/jacobsalmela/AdminLTE#pi-hole-admin-dashboard) will be installed automatically so you can view stats and change settings.  You can find it at:
+
+`http://192.168.1.x/admin/index.php`
+
+![Web](http://i.imgur.com/m114SCn.png)
 
 ##  Custom Config File
 If you want to use your own variables for the gravity script (i.e. storing the files in a different location) and don't want to have to change them every time there is an update to the script, create a file called `/etc/pihole/pihole.conf`. In it, you should add your own variables in a similar fashion as shown below:
 
 ```
-origin=/var/run/pihole
+piholeDir=/var/run/pihole
 adList=/etc/dnsmasq.d/adList
 ```

 ## Other Operating Systems
 This script will work for other UNIX-like systems with some slight **modifications**.  As long as you can install `dnsmasq` and a Webserver, it should work OK.  The automated install only works for a clean install of Raspiban right now since that is how the project originated.
