 Please read and understand the contribution guide before creating an issue or pull request.
 
-## Etiquette
+The guide can be found here: [https://docs.pi-hole.net/guides/github/contributing/](https://docs.pi-hole.net/guides/github/contributing/)
 
-- Our goal for Pi-hole is **stability before features**.  This means we focus on squashing critical bugs before adding new features.  Often, we can do both in tandem, but bugs will take priority over a new feature.
-- Pi-hole is open source and [powered by donations](https://pi-hole.net/donate/), and as such, we give our **free time** to build, maintain, and **provide user support** for this project.  It would be extremely unfair for us to suffer abuse or anger for our hard work, so please take a moment to consider that.
-- Please be considerate towards the developers and other users when raising issues or presenting pull requests.
-- Respect our decision(s), and do not be upset or abusive if your submission is not used.
 
-## Viability
-
-When requesting or submitting new features, first consider whether it might be useful to others. Open source projects are used by many people, who may have entirely different needs to your own. Think about whether or not your feature is likely to be used by other users of the project.
-
-## Procedure
-
-**Before filing an issue:**
-
-- Attempt to replicate and **document** the problem, to ensure that it wasn't a coincidental incident.
-- Check to make sure your feature suggestion isn't already present within the project.
-- Check the pull requests tab to ensure that the bug doesn't have a fix in progress.
-- Check the pull requests tab to ensure that the feature isn't already in progress.
-
-**Before submitting a pull request:**
-
-- Check the codebase to ensure that your feature doesn't already exist.
-- Check the pull requests to ensure that another person hasn't already submitted the feature or fix.
-- Read and understand the [DCO guidelines](https://github.com/pi-hole/pi-hole/wiki/Contributing-to-the-project) for the project.
-
-## Technical Requirements
-
-- Submit Pull Requests to the **development branch only**.
-- Before Submitting your Pull Request, merge `development` with your new branch and fix any conflicts. (Make sure you don't break anything in development!)
-- Please use the [Google Style Guide for Shell](https://google.github.io/styleguide/shell.xml) for your code submission styles. 
-- Commit Unix line endings.
-- Please use the Pi-hole brand: **Pi-hole** (Take a special look at the capitalized 'P' and a low 'h' with a hyphen)
-- (Optional fun) keep to the theme of Star Trek/black holes/gravity.

 ## One-Step Automated Install

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

Therefore, we provide these alternative installation methods which allow code review before installation:

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
+## [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) which ensures 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); just be sure to disable DHCP on your router first (if it has that feature available).

 We welcome _everyone_ to contribute to issue reports, suggest new features, and create pull requests.
 
-If you have something to add - anything from a typo through to a whole new feature, we're happy to check it out! Just make sure to fill out our template when submitting your request; the questions that it asks will help the volunteers quickly understand what you're aiming to achieve.

 You'll find that the [install script](https://github.com/pi-hole/pi-hole/blob/master/automated%20install/basic-install.sh) and the [debug script](https://github.com/pi-hole/pi-hole/blob/master/advanced/Scripts/piholeDebug.sh) have an abundance of comments, which will help you better understand how Pi-hole works. They're also a valuable resource to those who want to learn how to write scripts or code a program! We encourage anyone who likes to tinker to read through it and submit a pull request for us to review.

 ## Breakdown of Features
-### The Command Line Interface
-The `pihole` command has all the functionality necessary to be able to fully administer the Pi-hole, without the need of the Web Interface. It's fast, user-friendly, and auditable by anyone with an understanding of `bash`.

+### [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 Web Interface Dashboard
+
 This [optional dashboard](https://github.com/pi-hole/AdminLTE) 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!
 
-<img src="https://pi-hole.github.io/graphics/Screenshots/pihole-dashboard.png"  alt="Pi-hole Dashboard"/></a>
-
 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!

-## The Origin Of Pi-hole
-Pi-hole being an **advertising-aware DNS/Web server**, makes use of the following technologies:
-
-* [`dnsmasq`](http://www.thekelleys.org.uk/dnsmasq/doc.html) - a lightweight DNS and DHCP server
-* [`curl`](https://curl.haxx.se) - A command line tool for transferring data with URL syntax
-* [`lighttpd`](https://www.lighttpd.net) - web server designed and optimized for high performance
-* [`php`](https://secure.php.net) - a popular general-purpose web scripting language
-* [AdminLTE Dashboard](https://github.com/almasaeed2010/AdminLTE) - premium admin control panel based on Bootstrap 3.x
-
-While quite outdated at this point, [this original blog post about Pi-hole](https://jacobsalmela.com/2015/06/16/block-millions-ads-network-wide-with-a-raspberry-pi-hole-2-0/) goes into **great detail** about how Pi-hole was originally set up and how it works. Syntactically, it's no longer accurate, but the same basic principles and logic still apply to Pi-hole's current state.
