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
 ```
 
-## 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).

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

+FTLDNS 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:

-## The Origin Of Pi-hole
-Pi-hole being a **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) - webserver 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-While quite outdated at this point, [this original blog post about Pi-hole](https://jacobsalmela.com/2015/06/16/block-millions-ads-network-wide-with-a-raspberry-pi-hole-2-0/) goes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 setup 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.

+Pi-hole : The Faster-Than-Light (FTL) Engine is a lightweight, purpose-built daemon used to provide statistics needed for the Pi-hole Web Interface, and its API can be easily integrated into your own projects. Although it is an optional component of the Pi-hole ecosystem, it will be installed by default to provide statistics. As the name implies, FTL does its work \fIvery\fR \fIquickly\fR!
+.br
+

+# Recommended way to run tests
+
+Make sure you have Docker and Python w/pip package manager.
+
+From command line all you need to do is:
+
+- `pip install tox`
+- `tox`
+
+Tox handles setting up a virtual environment for python dependencies, installing dependencies, building the docker images used by tests, and finally running tests.  It's an easy way to have travis-ci like build behavior locally.
+
+## Alternative py.test method of running tests
+
+You're responsible for setting up your virtual env and dependencies in this situation.
+
+```
+py.test -vv -n auto -m "build_stage"
+py.test -vv -n auto -m "not build_stage"
+```
+
+The build_stage tests have to run first to create the docker images, followed by the actual tests which utilize said images.  Unless you're changing your dockerfiles you shouldn't have to run the build_stage every time - but it's a good idea to rebuild at least once a day in case the base Docker images or packages change.
+
+# How do I debug python?
+
+Highly recommended: Setup PyCharm on a **Docker enabled** machine.  Having a python debugger like PyCharm changes your life if you've never used it :)
