+## Forking and Cloning from GitHub to GitHub
+
+1. Fork <https://github.com/pi-hole/pi-hole/> to a repo under a namespace you control, or have permission to use, for example: `https://github.com/<your_namespace>/<your_repo_name>/`. You can do this from the github.com website.
+2. Clone `https://github.com/<your_namespace>/<your_repo_name>/` with the tool of you choice.
+3. To keep your fork in sync with our repo, add an upstream remote for pi-hole/pi-hole to your repo.
+
+    ```bash
+    git remote add upstream https://github.com/pi-hole/pi-hole.git
+    ```
+
+4. Checkout the `development` branch from your fork `https://github.com/<your_namespace>/<your_repo_name>/`.
+5. Create a topic/branch, based on the `development` branch code. *Bonus fun to keep to the theme of Star Trek/black holes/gravity.*
+6. Make your changes and commit to your topic branch in your repo.
+7. Rebase your commits and squash any insignificant commits. See the notes below for an example.
+8. Merge `development` your branch and fix any conflicts.
+9. Open a Pull Request to merge your topic branch into our repo's `development` branch.
+
+- Keep in mind the technical requirements from above.
+
+## Forking and Cloning from GitHub to other code hosting sites
+
+- Forking is a GitHub concept and cannot be done from GitHub to other git-based code hosting sites. However, those sites may be able to mirror a GitHub repo.
+
+1. To contribute from another code hosting site, you must first complete the steps above to fork our repo to a GitHub namespace you have permission to use, for example: `https://github.com/<your_namespace>/<your_repo_name>/`.
+2. Create a repo in your code hosting site, for example: `https://gitlab.com/<your_namespace>/<your_repo_name>/`
+3. Follow the instructions from your code hosting site to create a mirror between `https://github.com/<your_namespace>/<your_repo_name>/` and `https://gitlab.com/<your_namespace>/<your_repo_name>/`.
+4. When you are ready to create a Pull Request (PR), follow the steps `(starting at step #6)` from [Forking and Cloning from GitHub to GitHub](#forking-and-cloning-from-github-to-github) and create the PR from `https://github.com/<your_namespace>/<your_repo_name>/`.
+
+## Notes for squashing commits with rebase
+
+- To rebase your commits and squash previous commits, you can use:
+
+    ```bash
+    git rebase -i your_topic_branch~(number of commits to combine)
+    ```
+
+- For more details visit [gitready.com](http://gitready.com/advanced/2009/02/10/squashing-commits-with-rebase.html)
+
+1. The following would combine the last four commits in the branch `mytopic`.
+
+    ```bash
+    git rebase -i mytopic~4
+    ```
+
+2. An editor window opens with the most recent commits indicated: (edit the commands to the left of the commit ID)
+
+    ```gitattributes
+    pick 9dff55b2 existing commit comments
+    squash ebb1a730 existing commit comments
+    squash 07cc5b50 existing commit comments
+    reword 9dff55b2 existing commit comments
+    ```
+
+3. Save and close the editor. The next editor window opens: (edit the new commit message). *If you select reword for a commit, an additional editor window will open for you to edit the comment.*
+
+    ```bash
+    new commit comments
+    Signed-off-by: yourname <your email address>
+    ```
+
+4. Save and close the editor for the rebase process to execute. The terminal output should say something like the following:
+
+    ```bash
+    Successfully rebased and updated refs/heads/mytopic.
+    ```
+
+5. Once you have a successful rebase, and before you sync your local clone, you have to force push origin to update your repo:
+
+    ```bash
+    git push -f origin
+    ```
+
+6. Continue on from step #7 from [Forking and Cloning from GitHub to GitHub](#forking-and-cloning-from-github-to-github)

-#### `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:
 
 ### 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).

-## 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.

+    Change how (and if) hourly PTR requests are made to check for changes in client and upstream server hostnames:
+.br
+    IPV4 - Do the hourly PTR lookups only for IPv4 addresses resolving issues in networks with many short-lived PE IPv6 addresses.
+.br
+    ALL  - Do the hourly PTR lookups for all addresses. This can create a lot of PTR queries in networks with many IPv6 addresses.
+.br
+    NONE - Don't do hourly PTR lookups. Look up hostnames once (when first seeing a client) and never again. Future hostname changes may be missed.
+.br
+
+\fBMAXNETAGE=365\fR
+.br
+    IP addresses (and associated host names) older than the specified number of days are removed.
+.br
+    This avoids dead entries in the network overview table.
+.br
+
+\fBEDNS0_ECS=true|false\fR
+.br
+    Should we overwrite the query source when client information is provided through EDNS0 client subnet (ECS) information?

+\fBDBINTERVAL=1.0\fR
+.br
+    How often do we store queries in FTL's database [minutes]?
+.br
+    Accepts value between 0.1 (6 sec) and 1440 (1 day)
+.br
+
+\fBDBFILE=/etc/pihole/pihole-FTL.db\fR
+.br
+    Specify path and filename of FTL's SQLite long-term database.
+.br
+    Setting this to DBFILE= disables the database altogether
+.br
+
+\fBLOGFILE=/var/log/pihole-FTL.log\fR
+.br
+    The location of FTL's log file.
+.br
+
+\fBPIDFILE=/run/pihole-FTL.pid\fR

+.br
+
+\fBGRAVITYDB=/etc/pihole/gravity.db\fR
+.br
+    Specify path and filename of FTL's SQLite3 gravity database. This database contains all domains relevant for Pi-hole's DNS blocking.
+.br
+
+\fBDEBUG_ALL=false|true\fR
+.br
+    Enable all debug flags. If this is set to true, all other debug config options are ignored.
+.br
+
+\fBDEBUG_DATABASE=false|true\fR
+.br
+    Print debugging information about database actions such as SQL statements and performance.
+.br
+
+\fBDEBUG_NETWORKING=false|true\fR
+.br
+    Prints a list of the detected network interfaces on the startup of FTL.
+.br
+
+\fBDEBUG_LOCKS=false|true\fR
+.br
+    Print information about shared memory locks.
+.br
+    Messages will be generated when waiting, obtaining, and releasing a lock.
+.br

+.br
+    What is to be removed, how many have been removed and how long did GC take.
+.br
+
+\fBDEBUG_ARP=false|true\fR
+.br
+    Print information about ARP table processing:
+.br
+    How long did parsing take, whether read MAC addresses are valid, and if the macvendor.db file exists.
+.br
+
+\fBDEBUG_REGEX=false|true\fR
+.br
+    Controls if FTL should print extended details about regex matching.
+.br
+
+\fBDEBUG_API=false|true\fR
+.br
+    Print extra debugging information during telnet API calls.
+.br
+    Currently only used to send extra information when getting all queries.
+.br

+.br
+    Print information about overTime memory operations, such as initializing or moving overTime slots.
+.br
+
+\fBDEBUG_EXTBLOCKED=false|true\fR
+.br
+    Print information about why FTL decided that certain queries were recognized as being externally blocked.
+.br
+
+\fBDEBUG_CAPS=false|true\fR
+.br
+    Print information about POSIX capabilities granted to the FTL process.
+.br
+    The current capabilities are printed on receipt of SIGHUP i.e. after executing `killall -HUP pihole-FTL`.
+.br
+
+\fBDEBUG_DNSMASQ_LINES=false|true\fR
+.br
+    Print file and line causing a dnsmasq event into FTL's log files.
