+# Developer Tools Code of Conduct
+
+This file describes the Developer Tools (aka "DevTools") code of conduct.
+
+# Conduct
+
+We are committed to providing a friendly, safe and welcoming
+environment for all, regardless of level of experience, gender, gender
+identity and expression, sexual orientation, disability, personal
+appearance, body size, race, ethnicity, age, religion, nationality, or
+other similar characteristic.
+
+On IRC, please avoid using overtly sexual nicknames or other nicknames
+that might detract from a friendly, safe and welcoming environment for
+all.
+
+Please be kind and courteous. There’s no need to be mean or rude.
+
+Respect that people have differences of opinion and that every design
+or implementation choice carries a trade-off and numerous costs. There
+is seldom a right answer.
+
+We will exclude you from interaction if you insult, demean or harass
+anyone. That is not welcome behaviour. We interpret the term
+“harassment” as including the definition in the
+[Citizen Code of Conduct](http://citizencodeofconduct.org/); if you
+have any lack of clarity about what might be included in that concept,
+please read their definition. In particular, we don’t tolerate
+behavior that excludes people in socially marginalized groups.
+
+Private harassment is also unacceptable. No matter who you are, if you
+feel you have been or are being harassed or made uncomfortable by a
+community member, please contact one of the moderators (see below)
+immediately. Whether you’re a regular contributor or a newcomer, we
+care about making this community a safe place for you and we’ve got
+your back.
+
+Likewise any spamming, trolling, flaming, baiting or other
+attention-stealing behaviour is not welcome.
+
+# Moderation
+
+These are the policies for upholding our community’s standards of
+conduct. If you feel that a thread needs moderation, please use the
+point of contact for the medium in which you're communicating:
+
+* For one of the IRC channels, contact a channel operator (they
+  have an "@" in front of their names);
+* Bugzilla and the dev-developer-tools mailing list, contact
+  [inclusion@mozilla.com](mailto:inclusion@mozilla.com);
+* The debugger.html repository on GitHub has [its own code of conduct](https://github.com/devtools-html/debugger.html/blob/master/CODE_OF_CONDUCT.md), but you can also
+  email [inclusion@mozilla.com](mailto:inclusion@mozilla.com).
+
+Remarks that violate these standards of conduct, including hateful,
+hurtful, oppressive, or exclusionary remarks, are not
+allowed. (Cursing is allowed, but never targeting another user, and
+never in a hateful manner.)
+
+Remarks that moderators find inappropriate, whether listed in the code
+of conduct or not, are also not allowed.
+
+Moderators will first respond to such remarks with a warning.
+
+If the warning is unheeded, then on IRC the user will be “kicked,”
+i.e., kicked out of the communication channel to cool off.
+
+If the user comes back and continues to make trouble, they will be
+banned, i.e., indefinitely excluded.  On other communications media,
+such as bugzilla or mailing lists, it will be up to the moderator's
+discretion whether a user will be banned after the first warning.
+
+Moderators may choose at their discretion to un-ban the user if it was
+a first offense and they offer the offended party a genuine apology.
+
+If a moderator bans someone and you think it was unjustified, please
+take it up with that moderator, or with a different moderator, in
+private. Complaints about bans in-channel (or on the mailing list or
+in the bug tracker) are not allowed.
+
+Moderators are held to a higher standard than other community
+members. If a moderator creates an inappropriate situation, they
+should expect less leeway than others.
+
+In this community we strive to go the extra step to look out for
+each other. Don’t just aim to be technically unimpeachable, try to be
+your best self. In particular, avoid flirting with offensive or
+sensitive issues, particularly if they’re off-topic; this all too
+often leads to unnecessary fights, hurt feelings, and damaged trust;
+worse, it can drive people away from the community entirely.
+
+And if someone takes issue with something you said or did, resist the
+urge to be defensive. Just stop doing what it was they complained
+about and apologize. Even if you feel you were misinterpreted or
+unfairly accused, chances are good there was something you could’ve
+communicated better — remember that it’s your responsibility to make
+your fellow devtoolers comfortable. Everyone wants to get along and we
+are all here first and foremost because we want to talk about cool
+technology. You will find that people will be eager to assume good
+intent and forgive as long as you earn their trust.
+
+The enforcement policies listed above apply to all official DevTools
+venues; including official IRC channels (those starting with
+"#devtools"); GitHub repositories associated with DevTools; and
+DevTools bugs in bugzilla.
+
+# Also Applicable
+
+The
+[Mozilla Community Participation Guidelines](https://www.mozilla.org/en-US/about/governance/policies/participation/)
+also apply.  Please read these as well.

+# History
+
+This was derived from the
+[Rust Code of Conduct](https://www.rust-lang.org/en-US/conduct.html).
