Subject: [PATCH 01/20] ugly hack to whitelist from the Web interface

I wanted the whitelist feature to keep the user on the same page
without having to reload it.  I'm sure someone better versed in PHP
could eliminate the need for this hack.  Nonetheless, it works.

www-data runs the script if executed from the Web interface.  www-data
also needs access to write to /etc/pihole/gravity.list to actually
remove the domain.  So a few more things need to happen before this
will fully work.

The changes in this script won't change what is displayed if run from
the terminal, but will help when it needs to be run from the Web
interface, so I am just committing this now.

The only other thing I would like to see would be a progress spinner,
but my Web skills still need some work...

+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/).
 
 ## Technical Details
 
+The Pi-hole is an **advertising-aware DNS/Web server**.  If an ad domain is queried, a small Web page or GIF is delivered in place of the advertisement.  You can also [replace ads with any image you want](http://pi-hole.net/faq/is-it-possible-to-change-the-blank-page-that-takes-place-of-the-ads-to-something-else/) since it is just a simple Webpage taking place of the ads.
+
 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 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
 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`
 
+### API
+
+A basic read-only API can be accessed at `/admin/api.php`. It returns the following JSON:
+```JSON
+{
+	"domains_being_blocked": "136708",
+	"dns_queries_today": "18108",
+	"ads_blocked_today": "14648",
+	"ads_percentage_today": 80.892423238348
+}
+```
+

-##  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:
+## Real-time Statistics
 
-```
-piholeDir=/var/run/pihole
-adList=/etc/dnsmasq.d/adList
-```
+You can view [real-time stats](http://pi-hole.net/faq/install-the-real-time-lcd-monitor-chronometer/) via `ssh` or on an [2.8" LCD screen](http://amzn.to/1P0q1Fj).  This is accomplished via [`chronometer.sh`](https://github.com/jacobsalmela/pi-hole/blob/master/advanced/Scripts/chronometer.sh).
 
-See the [Wiki](https://github.com/jacobsalmela/pi-hole/wiki/Customization) entry for more details.

-### How It Works
-A technical and detailed description can be found [here](http://jacobsalmela.com/block-millions-ads-network-wide-with-a-raspberry-pi-hole-2-0)!
+## Help
+- See the [Wiki](https://github.com/jacobsalmela/pi-hole/wiki/Customization) entry for more details
+- There is also an [FAQ section on pi-hole.net](http://pi-hole.net)
 
 ## 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.

Subject: [PATCH 18/20] leave system cron alone
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Taking JoshKastang’s idea from #153, the system cron file will be left
alone and the pihole.cron gets its own.
