# Automated Install
|
||||
|
||||
1. Install Raspbian
|
||||
2. Set a **static** IP address
|
||||
3. Run the command below
|
||||
|
||||
```curl -L install.pi-hole.net | bash```
|
||||
|
||||
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.

# Raspberry Pi Ad Blocker

The Pi-hole is a DNS/Web server that will **block ads for any device on your network**.

## 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).

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.

## 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:

## 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.
