# Code Of Conduct
2
-
3
-
This Code of Conduct is based heavily on "instruments of good works" from chapter 4 of The Rule of St. Benedict (hereafter: "The Rule"). This Rule has proven its mettle in thousands of diverse communities for over 1,500 years, and has served as a baseline for many civil law codes since the time of Charlemagne.
4
-
5
-
The Rule is strict, and none are able to comply perfectly. Grace is readily granted for minor transgressions. All are encourage to follow this rule closely, as in so doing they may expect to live happier, healthier, and more productive lives. The entire Rule is good and wholesome, and yet we make no enforcement of the more introspective aspects.
6
-
7
-
We view The Rule as our promise to all users of this project of how the developers are expected to behave. This is a one-way promise, or covenant. In other words, the developers are saying: "We will treat you this way regardless of how you treat us." We ask you to join us in this covenant through your interactions with this project.

1. Love the Lord God with all your heart, soul, mind, and strength.
12
-
1. Love your neighbor as yourself.
13
-
1. Do not steal or bear false witness.
14
-
1. Honor all people and treat them with the respect you desire.
15
-
1. Do not give way to anger or nurse grudges.
16
-
1. Speak truthfully and reject all forms of deceit.
17
-
1. Do not return evil for evil, and bear wrongs patiently. (that does not mean you must suffer abuse from others however)
18
-
1. Be humble, avoid pride, jealousy, and arrogance.
19
-
1. Respect the wisdom of those who are more experienced than you, recognizing that knowledge is earned through time and reflection.
20
-
1. Generously share your understanding with those who are still learning, approaching teaching with compassion, patience, and genuine care.
21
-
1. Settle disputes quickly and with care, ensuring that disagreements do not fester and grow beyond repair.
22
-
1. Never despair of mercy.

This code of conduct was adapted from [The rule of St. Benedict, as your Code of Conduct](https://github.com/saint-benedict/code-of-conduct) which in turn was adapted from [SQLite's Code of conduct](https://web.archive.org/web/20181024103452/https://sqlite.org/codeofconduct.html) and now [Code of Ethics](https://sqlite.org/codeofethics.html).

Hi there! I'm glad you decided to add something! I don't have a super strict contributing guideline but here are some things to keep in mind:
4
-
5
-
1. Please try to follow the existing style of code and documentation. I know this seems kinda obvious but its easy enough to forget when implementing a new feature!
6
-
2. Follow the CoC please 💖 It should be linked on this repo's home page but if not you can find it [here](https://github.com/taciturnaxolotl/carriage/blob/master/.github/CODE_OF_CONDUCT.md). The TLDR is be nice and don't be a jerk but then again so is the TLDR of most CoCs :)
7
-
3. Use conventional commits! I'm a big fan of the [Conventional Commits](https://www.conventionalcommits.org/en/v1.0.0/) standard. It makes it easier to track changes and generate changelogs. I tend to use it at a pretty basic level (feat|chore|bug|docs: <message>) but feel free to get as fancy as you want within the standard ^-^
8
-
4. Last one. Once you open a PR ping me plz 😄 I tend to forget to check my repos for PRs so a ping will remind me it exists and i'll get to it much quicker! Alternatively you can open the PR and wait 4-6 business months 💀
