|
||||
|
||||
As contributors and maintainers of this project, and in the interest of fostering an open
|
||||
and welcoming community, we pledge to respect all people who contribute through reporting
|
||||
issues, posting feature requests, updating documentation, submitting pull requests or
|
||||
patches, and other activities.
|
||||
|
||||
We are committed to making participation in this project a harassment-free experience for
|
||||
everyone, regardless of level of experience, gender, gender identity and expression,
|
||||
sexual orientation, disability, personal appearance, body size, race, ethnicity, age,
|
||||
religion, or nationality.
|
||||
|
||||
Examples of unacceptable behavior by participants include:
|
||||
|
||||
* The use of sexualized language or imagery
|
||||
* Personal attacks
|
||||
* Trolling or insulting/derogatory comments
|
||||
* Public or private harassment
|
||||
* Publishing other's private information, such as physical or electronic addresses,
|
||||
without explicit permission
|
||||
* Other unethical or unprofessional conduct
|
||||
|
||||
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.
|
||||
|
||||
By adopting this Code of Conduct, project maintainers commit themselves to fairly and
|
||||
consistently applying these principles to every aspect of managing this project. Project
|
||||
maintainers who do not follow or enforce the Code of Conduct may be permanently removed
|
||||
from the project team.
|
||||
|
||||
This Code of Conduct applies both within project spaces and in public spaces when an
|
||||
individual is representing the project or its community.
|
||||
|
||||
Instances of abusive, harassing, or otherwise unacceptable behavior may be reported by
|
||||
contacting a project maintainer at spring-code-of-conduct@pivotal.io . All complaints will
|
||||
be reviewed and investigated and will result in a response that is deemed necessary and
|
||||
appropriate to the circumstances. Maintainers are obligated to maintain confidentiality
|
||||
with regard to the reporter of an incident.
|
||||
