-# 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,
-education, socio-economic status, 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 Dan Buch at dan@meatballhat.com. All complaints will be
-reviewed and investigated and will result in a response that is deemed necessary
-and 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 https://www.contributor-covenant.org/version/1/4/code-of-conduct.html

-
-cli is a simple, fast, and fun package for building command line apps in Go. The
-goal is to enable developers to write fast and distributable command line
-applications in an expressive way.
-
-## Usage Documentation
-
-Usage documentation exists for each major version
-
-- `v1` - [./docs/v1/manual.md](./docs/v1/manual.md)
-- `v2` - 🚧 documentation for `v2` is WIP 🚧
-
-## Installation
-
-Make sure you have a working Go environment.  Go version 1.10+ is supported.  [See
-the install instructions for Go](http://golang.org/doc/install.html).
-
-### GOPATH
-
-Make sure your `PATH` includes the `$GOPATH/bin` directory so your commands can
-be easily used:
-```
-export PATH=$PATH:$GOPATH/bin
-```
-
-### Supported platforms
-
-cli is tested against multiple versions of Go on Linux, and against the latest
-released version of Go on OS X and Windows.  For full details, see
-[`./.travis.yml`](./.travis.yml) and [`./appveyor.yml`](./appveyor.yml).
-
-### Using `v1` releases
-
-```
-$ go get github.com/urfave/cli
-```
-
-```go
-...
-import (
-  "github.com/urfave/cli"
-)
-...
-```
-
-### Using `v2` releases
-
-**Warning**: `v2` is in a pre-release state.
-
-```
-$ go get github.com/urfave/cli.v2
-```
-
-```go
-...
-import (
-  "github.com/urfave/cli.v2" // imports as package "cli"
-)
-...
-```
