+# Contributor Covenant Code of Conduct
+
+## Our Pledge
+
+In the interest of fostering an open and welcoming environment, we as
+contributors and maintainers pledge to make participation in our project and
+our community a harassment-free experience for everyone, regardless of age, body
+size, disability, ethnicity, sex characteristics, 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 within all project spaces, and it also applies when
+an individual is representing the project or its community in public spaces.
+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 opensource@github.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.
+

+Hi there! We're thrilled that you'd like to contribute to this project. Your help is essential for keeping it great.
+
+Contributions to this project are [released](https://help.github.com/articles/github-terms-of-service/#6-contributions-under-repository-license) to the public under the [project's open source license](LICENSE).
+
+Please note that this project is released with a [Contributor Code of Conduct][code-of-conduct]. By participating in this project you agree to abide by its terms.
+
+## Found a bug?
+
+- **Ensure the bug was not already reported** by searching on GitHub under [Issues](https://github.com/actions/upload-artifact/issues).
+- If you're unable to find an open issue addressing the problem, [open a new one](https://github.com/actions/upload-artifact/issues/new). Be sure to include a **title and clear description**, as much relevant information as possible, and a **code sample** or a **reproducable test case** demonstrating the expected behavior that is not occurring.
+- If possible, use the relevant bug report templates to create the issue.
+
+## What should I know before submitting a pull request or issue
+
+The code related to `upload-artifact` is split between this repository and [actions/toolkit](https://github.com/actions/toolkit) where the `@actions/artifact` npm package is housed. The npm package contains the core functionality to interact with artifacts. Any extra functionality on top of interacting with the apis such as search is inside this repository.
+Artifact related issues will be tracked in this repository so please do not open duplicate issues in `actions/toolkit`.
+
+## Submitting a pull request
+
+1. [Fork][fork] and clone the repository
+2. Configure and install the dependencies: `npm install`
+3. Make sure the tests pass on your machine: `npm run test`
+4. Create a new branch: `git checkout -b my-branch-name`
+5. Make your change, add tests, and make sure the tests still pass
+6. Make sure your code is correctly formatted: `npm run format`
+7. Make sure your code passes linting: `npm run lint`
+8. Update `dist/index.js` using `npm run release`. This creates a single javascript file that is used as an entry-point for the action
+7. Push to your fork and [submit a pull request][pr]
+8. Pat your self on the back and wait for your pull request to be reviewed and merged.
+
+Here are a few things you can do that will increase the likelihood of your pull request being accepted:
+
+- Write tests.
+- Keep your change as focused as possible. If there are multiple changes you would like to make that are not dependent upon each other, consider submitting them as separate pull requests.
+- Write a [good commit message](http://tbaggery.com/2008/04/19/a-note-about-git-commit-messages.html).

+If multiple paths are provided as input, the least common ancestor of all the search paths will be used as the root directory of the artifact. Exclude paths do not effect the directory structure.
 
 Relative and absolute file paths are both allowed. Relative paths are rooted against the current working directory. Paths that begin with a wildcard character should be quoted to avoid being interpreted as YAML aliases.

 With the following example, the available artifact (named `artifact` which is the default if no name is provided) would contain both `world.txt` (`hello`) and `extra-file.txt` (`howdy`).

+In the above example, four jobs will upload four different files to the same artifact but there will only be one file available when `my-artifact` is downloaded. Each job overwrites what was previously uploaded. To ensure that jobs don't overwrite existing artifacts, use a different name per job.
