1
+ # 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, gender identity and expression, level of experience,
9
+ nationality, personal appearance, race, religion, or sexual identity and
10
+ 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 ysat.tap@gmail.com. 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
+ ## Attribution

+
70
+ This Code of Conduct is adapted from the [Contributor Covenant][homepage], version 1.4,
71
