+## 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)

+    Should FTL only analyze A and AAAA queries?
+.br
+
+\fBSOCKET_LISTENING=localonly|all\fR
+.br
+    Listen only for local socket connections on the API port or permit all connections.
+.br
+
+\fBFTLPORT=4711\fR
+.br
+    On which port should FTL be listening?
+.br
+
+\fBRESOLVE_IPV6=yes|no\fR
+.br
+    Should FTL try to resolve IPv6 addresses to hostnames?
+.br
+
+\fBRESOLVE_IPV4=yes|no\fR
+.br
+    Should FTL try to resolve IPv4 addresses to hostnames?
+.br
+
+\fBDELAY_STARTUP=0\fR
+.br
+    Time in seconds (between 0 and 300) to delay FTL startup.

+.br
+    Can be disabled altogether by setting a value of -999.
+.br
+
+\fBNAMES_FROM_NETDB=true|false\fR
+.br
+    Control whether FTL should use a fallback option and try to obtain client names from checking the network table.
+.br
+    E.g. IPv6 clients without a hostname will be compared via MAC address to known clients.
+.br
+
+\fB\fBREFRESH_HOSTNAMES=IPV4|ALL|NONE\fR
+.br
+    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?

+    Parse ARP cache to fill network overview table.
+.br
+
+\fBDBIMPORT=yes|no\fR
+.br
+    Should FTL load information from the database on startup to be aware of the most recent history?
+.br
+
+\fBMAXDBDAYS=365\fR
+.br
+    How long should queries be stored in the database? Setting this to 0 disables the database
+.br
+
+\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

+.br
+
+\fBLOGFILE=/var/log/pihole-FTL.log\fR
+.br
+    The location of FTL's log file.
+.br
+
+\fBPIDFILE=/run/pihole-FTL.pid\fR

+.br
+
+\fBMACVENDORDB=/etc/pihole/macvendor.db\fR
+.br
+    The database containing MAC -> Vendor information for the network table.
+.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

+    Print information about garbage collection (GC):
+.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
+    Print information about overTime memory operations, such as initializing or moving overTime slots.
+.br

+    Print information about why FTL decided that certain queries were recognized as being externally blocked.
+.br
+
+\fBDEBUG_CAPS=false|true\fR
+.br
