<!-- markdownlint-enable MD033 -->

The Pi-hole® is a [DNS sinkhole](https://en.wikipedia.org/wiki/DNS_Sinkhole) that protects your devices from unwanted content without installing any client-side software.

- **Easy-to-install**: our dialogs walk you through the simple installation process in less than ten minutes
- **Resolute**: content is blocked in _non-browser locations_, such as ad-laden mobile apps and smart TVs
- **Responsive**: seamlessly speeds up the feel of everyday browsing by caching DNS queries
- **Lightweight**: runs smoothly with [minimal hardware and software requirements](https://docs.pi-hole.net/main/prerequisites/)
- **Robust**: a command-line interface that is quality assured for interoperability
- **Insightful**: a beautiful responsive Web Interface dashboard to view and control your Pi-hole
- **Versatile**: can optionally function as a [DHCP server](https://discourse.pi-hole.net/t/how-do-i-use-pi-holes-built-in-dhcp-server-and-why-would-i-want-to/3026), ensuring _all_ your devices are protected automatically
- **Scalable**: [capable of handling hundreds of millions of queries](https://pi-hole.net/2017/05/24/how-much-traffic-can-pi-hole-handle/) when installed on server-grade hardware
- **Modern**: blocks ads over both IPv4 and IPv6
- **Free**: open source software that helps ensure _you_ are the sole person in control of your privacy

## One-Step Automated Install

Those who want to get started quickly and conveniently may install Pi-hole using the following command:

### `curl -sSL https://install.pi-hole.net | bash`

## Alternative Install Methods

Piping to `bash` is [controversial](https://pi-hole.net/2016/07/25/curling-and-piping-to-bash), as it prevents you from [reading code that is about to run](https://github.com/pi-hole/pi-hole/blob/master/automated%20install/basic-install.sh) on your system. Therefore, we provide these alternative installation methods which allow code review before installation:

### Method 1: Clone our repository and run

```bash
git clone --depth 1 https://github.com/pi-hole/pi-hole.git Pi-hole
cd "Pi-hole/automated install/"
sudo bash basic-install.sh
```

### Method 2: Manually download the installer and run

```bash
wget -O basic-install.sh https://install.pi-hole.net
sudo bash basic-install.sh
```

### Method 3: Using Docker to deploy Pi-hole

Please refer to the [Pi-hole docker repo](https://github.com/pi-hole/docker-pi-hole) to use the Official Docker Images.

## [Post-install: Make your network take advantage of Pi-hole](https://docs.pi-hole.net/main/post-install/)

Once the installer has been run, you will need to [configure your router to have **DHCP clients use Pi-hole as their DNS server**](https://discourse.pi-hole.net/t/how-do-i-configure-my-devices-to-use-pi-hole-as-their-dns-server/245). This router configuration will ensure that all devices connecting to your network will have content blocked without any further intervention.

If your router does not support setting the DNS server, you can [use Pi-hole's built-in DHCP server](https://discourse.pi-hole.net/t/how-do-i-use-pi-holes-built-in-dhcp-server-and-why-would-i-want-to/3026); be sure to disable DHCP on your router first (if it has that feature available).

As a last resort, you can manually set each device to use Pi-hole as their DNS server.

## Breakdown of Features

### [Faster-than-light Engine](https://github.com/pi-hole/ftl)

[FTLDNS](https://github.com/pi-hole/ftl) is a lightweight, purpose-built daemon used to provide statistics needed for the Web Interface, and its API can be easily integrated into your own projects. As the name implies, FTLDNS does this all _very quickly_!

Some of the statistics you can integrate include:

- Total number of domains being blocked
- Total number of DNS queries today
- Total number of ads blocked today
- Percentage of ads blocked
- Unique domains
- Queries forwarded (to your chosen upstream DNS server)
- Queries cached
- Unique clients

Access the API via [`telnet`](https://github.com/pi-hole/FTL), the Web (`admin/api.php`) and Command Line (`pihole -c -j`). You can find out [more details over here](https://discourse.pi-hole.net/t/pi-hole-api/1863).

### The Command-Line Interface

The [pihole](https://docs.pi-hole.net/core/pihole-command/) command has all the functionality necessary to fully administer the Pi-hole, without the need for the Web Interface. It's fast, user-friendly, and auditable by anyone with an understanding of `bash`.

Some notable features include:

- [Whitelisting, Blacklisting, and Regex](https://docs.pi-hole.net/core/pihole-command/#whitelisting-blacklisting-and-regex)
- [Debugging utility](https://docs.pi-hole.net/core/pihole-command/#debugger)
- [Viewing the live log file](https://docs.pi-hole.net/core/pihole-command/#tail)
- [Updating Ad Lists](https://docs.pi-hole.net/core/pihole-command/#gravity)
- [Querying Ad Lists for blocked domains](https://docs.pi-hole.net/core/pihole-command/#query)
- [Enabling and Disabling Pi-hole](https://docs.pi-hole.net/core/pihole-command/#enable-disable)
- ... and _many_ more!

You can read our [Core Feature Breakdown](https://docs.pi-hole.net/core/pihole-command/#pi-hole-core) for more information.

### The Web Interface Dashboard

This [optional dashboard](https://github.com/pi-hole/web) allows you to view stats, change settings, and configure your Pi-hole. It's the power of the Command Line Interface, with none of the learning curve!

Some notable features include:

- Mobile-friendly interface
- Password protection
- Detailed graphs and doughnut charts
- Top lists of domains and clients
- A filterable and sortable query log
- Long Term Statistics to view data over user-defined time ranges
- The ability to easily manage and configure Pi-hole features
- ... and all the main features of the Command Line Interface!

There are several ways to [access the dashboard](https://discourse.pi-hole.net/t/how-do-i-access-pi-holes-dashboard-admin-interface/3168):

1. `http://pi.hole/admin/` (when using Pi-hole as your DNS server)
2. `http://<IP_ADDRESS_OF_YOUR_PI_HOLE>/admin/`
