# Contributor Covenant Code of Conduct
2+
3+
## Our Pledge
4+
5+
In the interest of fostering an open and welcoming environment, we as
6+
contributors and maintainers pledge to making participation in our project and
7+
our community a harassment-free experience for everyone, regardless of age, body
8+
size, disability, ethnicity, sex characteristics, gender identity and expression,
9+
level of experience, education, socio-economic status, nationality, personal
10+
appearance, race, religion, or sexual identity and orientation.
11+
12+
## Our Standards
13+
14+
Examples of behavior that contributes to creating a positive environment
15+
include:
16+
17+
* Using welcoming and inclusive language
18+
* Being respectful of differing viewpoints and experiences
19+
* Gracefully accepting constructive criticism
20+
* Focusing on what is best for the community
21+
* Showing empathy towards other community members
22+
23+
Examples of unacceptable behavior by participants include:
24+
25+
* The use of sexualized language or imagery and unwelcome sexual attention or
26+
advances
27+
* Trolling, insulting/derogatory comments, and personal or political attacks
28+
* Public or private harassment
29+
* Publishing others' private information, such as a physical or electronic
30+
address, without explicit permission
31+
* Other conduct which could reasonably be considered inappropriate in a
32+
professional setting
33+
34+
## Our Responsibilities
35+
36+
Project maintainers are responsible for clarifying the standards of acceptable
37+
behavior and are expected to take appropriate and fair corrective action in
38+
response to any instances of unacceptable behavior.
39+
40+
Project maintainers have the right and responsibility to remove, edit, or
41+
reject comments, commits, code, wiki edits, issues, and other contributions
42+
that are not aligned to this Code of Conduct, or to ban temporarily or
43+
permanently any contributor for other behaviors that they deem inappropriate,
44+
threatening, offensive, or harmful.
45+
46+
## Scope
47+
48+
This Code of Conduct applies both within project spaces and in public spaces
49+
when an individual is representing the project or its community. Examples of
50+
representing a project or community include using an official project e-mail
51+
address, posting via an official social media account, or acting as an appointed
52+
representative at an online or offline event. Representation of a project may be
53+
further defined and clarified by project maintainers.
54+
55+
## Enforcement
56+
57+
Instances of abusive, harassing, or otherwise unacceptable behavior may be
58+
reported by contacting the project team at tech@techthoughts.info. All
59+
complaints will be reviewed and investigated and will result in a response that
60+
is deemed necessary and appropriate to the circumstances. The project team is
61+
obligated to maintain confidentiality with regard to the reporter of an incident.
62+
Further details of specific enforcement policies may be posted separately.
63+
64+
Project maintainers who do not follow or enforce the Code of Conduct in good
65+
faith may face temporary or permanent repercussions as determined by other
66+
members of the project's leadership.
67+
68+
