-> `git-quick-stats` is a simple and efficient way to access various statistics in a git repository.
->
-> Any git repository may contain tons of information about commits, contributors, and files. Extracting this information is not always trivial, mostly because there are a gadzillion options to a gadzillion git commands – I don’t think there is a single person alive who knows them all.

-git-quick-stats
-```
-
-Or
-
-```bash

-```
-
-### Git log since and until
-
-You can set the variables `_GIT_SINCE` and/or `_GIT_UNTIL` before running `git-quick-stats` to limit the git log. These work similar to git's built-in `--since` and `--until` log options.
-
-```bash
-export _GIT_SINCE="2017-01-20"
-export _GIT_UNTIL="2017-01-22"
-```
-
-Once set, run `git quick-stats` as normal. Note that this affects all stats that parse the git log history until unset.
-
-### Git log limit
-
-You can set variable `_GIT_LIMIT` for limited output. It will affect the "changelogs" and "branch tree" options.
-
-```bash
-export _GIT_LIMIT=20
-```
-
-### Git pathspec
-
-You can exclude a directory from the stats by using [pathspec](https://git-scm.com/docs/gitglossary#gitglossary-aiddefpathspecapathspec)
-
-```bash
-export _GIT_PATHSPEC=':!directory'
-```
-
-You can also exclude files from the stats. Note that it works with any alphanumeric, glob, or regex that git respects.
-
-```bash
-export _GIT_PATHSPEC=':!package-lock.json'
-```
-
-### Git merge view strategy
-
-You can set the variable `_GIT_MERGE_VIEW` to enable merge commits to be part of the stats by setting `_GIT_MERGE_VIEW` to `enable`. You can also choose to only show merge commits by setting `_GIT_MERGE_VIEW` to `exclusive`. Default is to not show merge commits. These work similar to git's built-in `--merges` and `--no-merges` log options. 
-
-```bash
-export _GIT_MERGE_VIEW="enable"
-export _GIT_MERGE_VIEW="exclusive"
-```
-
-### Color themes
-
-You can change to the legacy color scheme by toggling the variable `_MENU_THEME` between `default` and `legacy`
-
-```bash
-export _MENU_THEME=legacy
-```
-
-![legacyThemeScreenshot](https://user-images.githubusercontent.com/8818630/58364012-61e53800-7e7b-11e9-910a-aaff836260eb.png)

-
-* [`bsdmainutils`](https://packages.debian.org/sid/bsdmainutils) `apt install bsdmainutils`
-
-## FAQ
-
-*Q:* I get some errors after run git-quick-stats in cygwin like `/usr/local/bin/git-quick-stats: line 2: $'\r': command not found`
-
-*A:* You can run the dos2unix app in cygwin as follows: `/bin/dos2unix.exe /usr/local/bin/git-quick-stats`. This will convert the script from the CR-LF convention that Microsoft uses to the LF convention that UNIX, OS X, and Linux use. You should then should be able to run it as normal.

-## Contribution
-
-Want to contribute? Great! First, read this page.
-
-### Code reviews
-
-All submissions, including submissions by project members, require review.</br>
-We use GitHub pull requests for this purpose.
-
-### Some tips for good pull requests
-
-* Use our code </br>
-  When in doubt, try to stay true to the existing code of the project.
-* Write a descriptive commit message. What problem are you solving and what
-  are the consequences? Where and what did you test? Some good tips:
-  [here](http://robots.thoughtbot.com/5-useful-tips-for-a-better-commit-message)
-  and [here](https://www.kernel.org/doc/Documentation/SubmittingPatches).
-* If your PR consists of multiple commits which are successive improvements /
-  fixes to your first commit, consider squashing them into a single commit
-  (`git rebase -i`) such that your PR is a single commit on top of the current
-  HEAD. This make reviewing the code so much easier, and our history more
-  readable.

+Once set, run `git quick-stats` as normal. Note that this affects all stats that parse the git log history until unset.
+
+### Git log limit
+
+You can set variable `_GIT_LIMIT` for limited output. It will affect the "changelogs" and "branch tree" options. The default limit is `10`.
+
+```bash
+export _GIT_LIMIT=20
+```
+
+### Git tag
+
+You can set `_GIT_TAG` to define the default tag used by the "new contributors since tag" option.
+
+```bash
+export _GIT_TAG="foo"
+```
+
+### Git log options
+
+You can set `_GIT_LOG_OPTIONS` for [git log options](https://git-scm.com/docs/git-log#_options):
+
+```bash
+export _GIT_LOG_OPTIONS="--ignore-all-space --ignore-blank-lines"
+```
+
+### Git pathspec
+
+You can exclude a directory from the stats by using [pathspec](https://git-scm.com/docs/gitglossary#gitglossary-aiddefpathspecapathspec)
+
+```bash
+export _GIT_PATHSPEC=':!directory'
+```
+
+You can also exclude files from the stats. Note that it works with any alphanumeric, glob, or regex that git respects.
+
+```bash
+export _GIT_PATHSPEC=':!package-lock.json'
+```
+
+### Git merge view strategy
+
+You can set the variable `_GIT_MERGE_VIEW` to enable merge commits to be part of the stats by setting `_GIT_MERGE_VIEW` to `enable`. You can also choose to only show merge commits by setting `_GIT_MERGE_VIEW` to `exclusive`. Default is to not show merge commits. These work similar to git's built-in `--merges` and `--no-merges` log options.
+
+```bash
+export _GIT_MERGE_VIEW="enable"
+export _GIT_MERGE_VIEW="exclusive"
+```
+
+### Git branch
+
+You can set the variable `_GIT_BRANCH` to set the branch of the stats. Works with commands `--git-stats-by-branch` and `--csv-output-by-branch`.
+
+```bash
+export _GIT_BRANCH="master"
+```
+
+### Ignore authors
+
+You can set the variable `_GIT_IGNORE_AUTHORS` to filter out specific authors. It will affect the "All contributors", ""Suggested code reviewers" and "New contributors" options.
+
+```bash
+export _GIT_IGNORE_AUTHORS="(author@examle.com|username)"
+```
+
+### Sorting contribution stats
+
+You can sort contribution stats by field `name`, `commits`, `insertions`, `deletions`, or `lines` (total lines changed) and order (`asc`, `desc`). e.g.: `commits-desc`
+
+```bash
+export _GIT_SORT_BY="name-asc"
+```
+
+### Commit days
+
+You can set \_GIT_DAYS to set the number of days for the heatmap
+
+```bash
+export _GIT_DAYS=30
+```
+
+### Color themes
+
+You can change to the legacy color scheme by toggling the variable `_MENU_THEME` between `default` and `legacy`.
+You can completely disable the color theme by setting the `_MENU_THEME` variable to `none`.
+
+```bash
+export _MENU_THEME="legacy"
+# or
+export _MENU_THEME="none"
+```
+

+
+## Installation
+
+### Debian and Ubuntu
+
+If you are on at least Debian Bullseye or Ubuntu Focal you can use apt for installation:
+
+```bash
+apt install git-quick-stats
+```
+
+### UNIX and Linux
+
+```bash
+git clone https://github.com/git-quick-stats/git-quick-stats.git && cd git-quick-stats
+sudo make install
+```
+
+For uninstalling, open up the cloned directory and run
+
+```bash
+sudo make uninstall
+```
+
+For update/reinstall
+
+```bash
+sudo make reinstall
+```
+
+### macOS (homebrew)
+
+`git-quick-stats` requires GNU `date`. On macOS, install GNU coreutils:
+
+```bash
+brew install coreutils
+export PATH="$HOMEBREW_PREFIX/opt/coreutils/libexec/gnubin:$PATH"
+```
+
+The script auto-detects GNU date as either `date` or `gdate`, so exporting
+`gnubin` is optional for this project.
+
+From there, you can install via Homebrew as follows:
+
+```bash
+brew install git-quick-stats
+```
+
+Or you can follow the UNIX and Linux instructions if you wish.
+
+If you would like to default to using GNU coreutils system-wide, add
+`export PATH="$HOMEBREW_PREFIX/opt/coreutils/libexec/gnubin:$PATH"` to your
+applicable `~/.bash_profile`, `~/.zprofile`, or other relevant profile based
+on the shell of your choice.
+
+### FreeBSD
+
+`git-quick-stats` requires GNU `date`. On FreeBSD, install GNU coreutils:
+
+```bash
+pkg install coreutils
+```
+
+FreeBSD provides GNU date as `gdate`, and the script auto-detects it.
+
+### Windows
+
+If you are installing with Cygwin, use these scripts:
+
+- [installer](https://gist.github.com/arzzen/35e09866dfdadf2108b2420045739245)
+- [uninstaller](https://gist.github.com/arzzen/21c660014d0663b6c5710014714779d6)
+
+If you are wishing to use this with WSL, follow the UNIX and Linux instructions.
+
+### Docker
+
+You can use the Docker image provided:
+
+- Build: `docker build -t arzzen/git-quick-stats .`
+- Run interactive menu: `docker run --rm -it -v $(pwd):/git arzzen/git-quick-stats`
+- Docker pull command: `docker pull arzzen/git-quick-stats` [docker repository](https://hub.docker.com/r/arzzen/git-quick-stats)
+
+## System requirements
+
+- An OS with a Bash shell
+- GNU `date` available as either `date` or `gdate`
+- Tools we use:
+
+```bash
+awk
+basename
+cat
+column
+date
+echo
+git
+grep
+head
+printf
+seq
+sort
+tput
+tr
+uniq
+```
+
+### Dependencies
+
+- [`bsdextrautils`](https://packages.debian.org/sid/bsdextrautils) `apt install bsdextrautils`
+- [`coreutils`](https://packages.debian.org/sid/coreutils) `apt install coreutils`
+- [`gawk`](https://packages.debian.org/sid/gawk) `apt install gawk`
+- [`grep`](https://packages.debian.org/sid/grep) `apt install grep`
+- [`ncurses-bin`](https://packages.debian.org/sid/ncurses-bin) `apt install ncurses-bin`
+
+## FAQ
+
+_Q:_ I get some errors after run git-quick-stats in cygwin like `/usr/local/bin/git-quick-stats: line 2: $'\r': command not found`
+
+_A:_ You can run the dos2unix app in cygwin as follows: `/bin/dos2unix.exe /usr/local/bin/git-quick-stats`. This will convert the script from the CR-LF convention that Microsoft uses to the LF convention that UNIX, OS X, and Linux use. You should then should be able to run it as normal.
+
+_Q:_ How they could be used in a project with many git projects and statistics would show a summary of all git projects?
+
+_A:_ If you want to include submodule logs, you can try using the following: `export _GIT_LOG_OPTIONS="-p --submodule=log"`
+(more info about [git log --submodule](https://git-scm.com/docs/git-log#Documentation/git-log.txt---submoduleltformatgt))

+## Contribution
+
+Want to contribute? Great! First, read this page.
+
+### Code reviews
+
+All submissions, including submissions by project members, require review.</br>
+We use GitHub pull requests for this purpose.
+
+### Some tips for good pull requests
+
+- Use our code </br>
+  When in doubt, try to stay true to the existing code of the project.
+- Write a descriptive commit message. What problem are you solving and what
+  are the consequences? Where and what did you test? Some good tips:
+  [here](http://robots.thoughtbot.com/5-useful-tips-for-a-better-commit-message)
+  and [here](https://www.kernel.org/doc/Documentation/SubmittingPatches).
+- If your PR consists of multiple commits which are successive improvements /
+  fixes to your first commit, consider squashing them into a single commit
+  (`git rebase -i`) such that your PR is a single commit on top of the current
+  HEAD. This make reviewing the code so much easier, and our history more
+  readable.

+    For interactive mode: git-quick-stats
+
+DESCRIPTION
+    Any git repository contains tons of information about commits, contributors,
+    and files. Extracting this information is not always trivial, mostly because
+    of a gadzillion options to a gadzillion git commands.
+    
+    This program allows you to see detailed information about a git repository.
+
+GENERATE OPTIONS
+    -T, --detailed-git-stats
+        give a detailed list of git stats
+    -R, --git-stats-by-branch
+        see detailed list of git stats by branch
+    -c, --changelogs
+        see changelogs
+    -L, --changelogs-by-author
+        see changelogs by author
+    -S, --my-daily-stats
+        see your current daily stats
+    -V, --csv-output-by-branch
+        output daily stats by branch in CSV format
+    -j, --json-output
+        save git log as a JSON formatted file to a specified area
+
+LIST OPTIONS
+    -b, --branch-tree
+        show an ASCII graph of the git repo branch history
+    -D, --branches-by-date
+        show branches by date
+    -C, --contributors
+        see a list of everyone who contributed to the repo
+    -n, --new-contributors
+        list everyone who made their first contribution since a specified date
+    -N, --new-contributors-since-tag
+        list everyone who made their first contribution since a specified tag
+    -a, --commits-per-author
+        displays a list of commits per author
+    -d, --commits-per-day
+        displays a list of commits per day
+    -m, --commits-by-month
+        displays a list of commits per month
+    -Y, --commits-by-year
+        displays a list of commits per year
+    -w, --commits-by-weekday
+        displays a list of commits per weekday
+    -W, --commits-by-author-by-weekday
+        displays a list of commits per weekday by author
+    -o, --commits-by-hour
+        displays a list of commits per hour
+    -A, --commits-by-author-by-hour
+        displays a list of commits per hour by author
+    -z, --commits-by-timezone
+        displays a list of commits per timezone
+    -Z, --commits-by-author-by-timezone
+        displays a list of commits per timezone by author
+
+CALENDAR OPTIONS
+    -k, --commits-calendar-by-author
+        shows a calendar heatmap of commits per day-of-week per month for a given author
+    -H, --commits-heatmap
+        shows a heatmap of commits per day-of-week per month for the last 30 days
+
+SUGGEST OPTIONS
+    -r, --suggest-reviewers
+        show the best people to contact to review code
+    -h, -?, --help
+        display this help text in the terminal
+
+ADDITIONAL USAGE
+    You can set _GIT_SINCE and _GIT_UNTIL to limit the git time log
+        ex: export _GIT_SINCE=\"2017-01-20\"
+    You can set _GIT_LIMIT for limited output log
+        ex: export _GIT_LIMIT=20
+    You can set _GIT_LOG_OPTIONS for git log options
+        ex: export _GIT_LOG_OPTIONS=\"--ignore-all-space --ignore-blank-lines\"
+    You can exclude directories or files from the stats by using pathspec
+        ex: export _GIT_PATHSPEC=':!pattern'
+    You can set _GIT_MERGE_VIEW to view merge commits with normal commits
+        ex: export _GIT_MERGE_VIEW=enable
+    You can also set _GIT_MERGE_VIEW to only show merge commits
+        ex: export _GIT_MERGE_VIEW=exclusive
+    You can change to the legacy color scheme by toggling the variable \"_MENU_THEME\" between \"default\" and \"legacy\".
+    You can completely disable the color theme by setting the \"_MENU_THEME\" variable to \"none\".
+        ex: export _MENU_THEME=legacy
+    You can set _GIT_BRANCH to set the branch of the stats
+        ex: export _GIT_BRANCH=master
+    You can set _GIT_IGNORE_AUTHORS to filter out specific authors
+        ex: export _GIT_IGNORE_AUTHORS=\"(author1|author2)\"
+    You can sort contribution stats by field \"name\", \"commits\", \"insertions\", \"deletions\", or \"lines\" - total lines changed and order - \"asc\", \"desc\"
+        ex: export _GIT_SORT_BY=\"name-asc\"
+    You can set _GIT_DAYS to set the number of days for the heatmap
+        ex: export _GIT_DAYS=30"
