+# Contributor Covenant Code of Conduct
+
+## Our Pledge
+
+In the interest of fostering an open and welcoming environment, we as contributors and maintainers pledge to making participation in our project and our community a harassment-free experience for everyone, regardless of age, body size, disability, ethnicity, gender identity and expression, level of experience, nationality, personal appearance, race, religion, or sexual identity and orientation.
+
+## Our Standards
+
+Examples of behavior that contributes to creating a positive environment include:
+
+* Using welcoming and inclusive language
+* Being respectful of differing viewpoints and experiences
+* Gracefully accepting constructive criticism
+* Focusing on what is best for the community
+* Showing empathy towards other community members
+
+Examples of unacceptable behavior by participants include:
+
+* The use of sexualized language or imagery and unwelcome sexual attention or advances
+* Trolling, insulting/derogatory comments, and personal or political attacks
+* Public or private harassment
+* Publishing others' private information, such as a physical or electronic address, without explicit permission
+* Other conduct which could reasonably be considered inappropriate in a professional setting
+
+## Our Responsibilities
+
+Project maintainers are responsible for clarifying the standards of acceptable behavior and are expected to take appropriate and fair corrective action in response to any instances of unacceptable behavior.
+
+Project maintainers have the right and responsibility to remove, edit, or reject comments, commits, code, wiki edits, issues, and other contributions that are not aligned to this Code of Conduct, or to ban temporarily or permanently any contributor for other behaviors that they deem inappropriate, threatening, offensive, or harmful.
+
+## Scope
+
+This Code of Conduct applies both within project spaces and in public spaces when an individual is representing the project or its community. Examples of representing a project or community include using an official project e-mail address, posting via an official social media account, or acting as an appointed representative at an online or offline event. Representation of a project may be further defined and clarified by project maintainers.
+
+## Enforcement
+
+Instances of abusive, harassing, or otherwise unacceptable behavior may be reported by contacting the project team at lukas.mestan@googlemail.com. The project team will review and investigate all complaints, and will respond in a way that it deems appropriate to the circumstances. The project team is obligated to maintain confidentiality with regard to the reporter of an incident. Further details of specific enforcement policies may be posted separately.
+
+Project maintainers who do not follow or enforce the Code of Conduct in good faith may face temporary or permanent repercussions as determined by other members of the project's leadership.
+
+## Attribution
+
+This Code of Conduct is adapted from the [Contributor Covenant][homepage], version 1.4, available at [http://contributor-covenant.org/version/1/4][version]

 > `git quick-stats` is a simple and efficient way to access various statistics in git repository.
 
-## Example
+> 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 – I don’t think there is a single person  alive who knows them all.  Probably not even [Linus Torvalds](https://github.com/torvalds) himself :).

+#### Git log since / until
 
 You can set variable `_GIT_SINCE`, `_GIT_UNTIL` and limit the git log
 
-eg:
+```bash
-
+export _GIT_SINCE="2017-20-01"
-`export _GIT_SINCE="2017-20-01"`
+export _GIT_UNTIL="2017-22-01"
-
+```
-`export _GIT_UNTIL="2017-22-01"`
 
 then run `git quick-stats` (affect all stats, except "My daily status" and "Git changelogs" )
 
+
+#### Git log limit
+
+You can set variable `_GIT_LIMIT` for limited output (it will affect: "Git changelogs" and "Branch tree view" )
+
+```bash
+export _GIT_LIMIT=20
+```
+
+#### Git pathspec
+
+You can exclude directory from the stats by using [pathspec](https://git-scm.com/docs/gitglossary#gitglossary-aiddefpathspecapathspec)
+
+```bash
+export _GIT_PATHSPEC=':!directory'

+## 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`

+NAME
+    ${program} - Simple and efficient way to access various stats in a git repo
+
+SYNOPSIS
+    For non-interactive mode: ${program} [OPTIONS]
+    For interactive mode: ${program}
+
+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.
+
+OPTIONS
+    -r, --suggest-reviewers
+        show the best people to contact to review code
+    -T, --detailed-git-stats
+        give a detailed list of git stats
+    -d, --commits-per-day
+        displays a list of commits per day
+    -m, --commits-by-month
+        displays a list of commits per month
+    -w, --commits-by-weekday
+        displays a list of commits per weekday
+    -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
+    -a, --commits-per-author
+        displays a list of commits per author
+    -S, --my-daily-stats
+        see your current daily stats
+    -C, --contributors
+        see a list of everyone who contributed to the repo
+    -b, --branch-tree
+        show an ASCII graph of the git repo branch history
+    -D, --branches-by-date
+        show branches by date
+    -c, --changelogs
+        see changelogs
+    -L, --changelogs-by-author
+        see changelogs by author
+    -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=\"2017-20-01\"
+    You can set _GIT_LIMIT for limited output log
+        ex: export _GIT_LIMIT=20
+    You can exclude a directory from the stats by using pathspec
+        ex: export _GIT_PATHSPEC=':!directory'"
