This is not a document you should strictly abide. Frankly speaking it is not a document at all. It's just a bunch of rules some authors follow.
I try to create my own content and avoid reprints.
By publishing the content of other authors (graphics, text) I always refer to sources.
I do not create stupid comments like "+1" or "LooooL".
I don't use obscene words and humiliate anyone.
I put maximum effort to ensure that my text is written without mistakes.
I respect the administration and users of the website, and I do not want to humiliate or insult them.
When arguing I try not to inflate the conflict but to solve the problem independently in direct messages.
If I can't solve a conflict I do not call users to bully and don't do it myself.
It's totally up to me whether to publish my content on Habr or not, and I do not expect any reward for it.
I help newbies on Habr if necessary .
I first use search to clarify if similar content has been published earlier by anyone. If so I'll complement that in comments.
I try to bring order instead of chaos on Habr.
I do not want to destroy or discredit the community.
I don't beg for karma and I'm comfortable with rating changes.
I try to take into account readers' feedback.
I think positive. There is always a way out of the difficult situation.
I understand that Habr is a community of people with different interests, and if some topic is not interesting to me, I do not prevent others from discussing it.
