CONDUCT.md

+## Conduct
+
+* We are committed to providing a friendly, safe and welcoming
+  environment for all, regardless of gender, sexual orientation,
+  disability, ethnicity, religion, or similar personal 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.
+
+* Please keep unstructured critique to a minimum. If you have solid
+  ideas you want to experiment with, make a fork and see how it works.
+
+* 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 <a
+  href="http://citizencodeofconduct.org/">Citizen Code of Conduct</a>;
+  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 channel ops or any of the
+  Syncthing core team 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 in our communication channels, most notably in Syncthing-related
+IRC channels and on the web forum.
+
+1. Remarks that violate the Syncthing 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.)
+
+2. Remarks that moderators find inappropriate, whether listed in the
+   code of conduct or not, are also not allowed.
+
+3. Moderators will first respond to such remarks with a warning.
+
+4. If the warning is unheeded, the user will be "kicked," i.e., kicked
+   out of the communication channel to cool off.
+
+5. If the user comes back and continues to make trouble, they will be
+   banned, i.e., indefinitely excluded.
+
+6. 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.
+
+7. 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 are not allowed.
+
+8. 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 the Syncthing 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
+community members 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.

-Please do contribute!
+## Reporting Bugs
+
+Please file bugs in the [Github Issue
+Tracker](https://github.com/syncthing/syncthing/issues). Include at
+least the following:
+
+ - What happened
+
+ - What did you expect to happen instead of what *did* happen, if it's
+   not crazy obvious
+
+ - What operating system, operating system version and version of
+   Syncthing you are running
+
+ - The same for other connected devices, where relevant
+
+ - Screenshot if the issue concerns something visible in the GUI
+
+ - Console log entries, where possible and relevant
+
+If you're not sure whether something is relevant, erring on the side of
+too much information will never get you yelled at. :)
+
+## Contributing Translations
+
+All translations are done via
+[Transifex](https://www.transifex.com/projects/p/syncthing/). If you
+wish to contribute to a translation, just head over there and sign up.
+Before every release, the language resources are updated from the
+latest info on Transifex.
+
+## Contributing Code
+
+Every contribution is welcome. If you want to contribute but are unsure
+where to start, any open issues are fair game! Be prepared for a
+[certain amount of review](http://docs.syncthing.net/dev/intro.html#why-are-you-being-so-hard-on-my-pull-request);
+it's all in the name of quality. :) Following the points below will make this
+a smoother process.
+
+Individuals making significant and valuable contributions are given
+commit-access to the project. If you make a significant contribution and
+are not considered for commit-access, please contact any of the
+Syncthing core team members.
+
+All nontrivial contributions should go through the pull request
+mechanism for internal review. Determining what is "nontrivial" is left
+at the discretion of the contributor.
+
+### Authorship
+
+All code authors are listed in the AUTHORS file. Commits must be made
+with the same name and email as listed in the AUTHORS file. To
+accomplish this, ensure that your git configuration is set correctly
+prior to making your first commit;
+
+    $ git config --global user.name "Jane Doe"
+    $ git config --global user.email janedoe@example.com
+
+You must be reachable on the given email address. If you do not wish to
+use your real name for whatever reason, using a nickname or pseudonym is
+perfectly acceptable.
+
+### Core Team
+
+The Syncthing core team currently consists of the following members;
+
+ - Jakob Borg (@calmh)
+ - Audrius Butkevicius (@AudriusButkevicius)
+
+## Coding Style
+
+- Follow the conventions laid out in [Effective Go](https://golang.org/doc/effective_go.html)
+  as much as makes sense.
+
+- All text files use Unix line endings.
+
+- Each commit should be `go fmt` clean.
+
+- The commit message subject should be a single short sentence
+  describing the change, starting with a capital letter.
+
+- Commits that resolve an existing issue must include the issue number
+  as `(fixes #123)` at the end of the commit message subject.
+
+- Imports are grouped per `goimports` standard; that is, standard
+  library first, then third party libraries after a blank line.
+
+- A contribution solving a single issue or introducing a single new
+  feature should probably be a single commit based on the current
+  `master` branch. You may be asked to "rebase" or "squash" your pull
+  request to make sure this is the case, especially if there have been
+  amendments during review.
+
+## Licensing
+
+All contributions are made under the same MPLv2 license as the rest of
+the project, except documentation, user interface text and translation
+strings which are licensed under the Creative Commons Attribution 4.0
+International License. You retain the copyright to code you have
+written.
+
+When accepting your first contribution, the maintainer of the project
+will ensure that you are added to the AUTHORS file, the NICKS file and
+the list of authors in the about box.
 
 ## Building
 
-[See the wiki](https://github.com/calmh/syncthing/wiki/Building)
+[See the documentation](http://docs.syncthing.net/dev/building.html)
+on how to get started with a build environment.
+
+## Branches
+
+ - `master` is the main branch containing good code that will end up in
+   the next release. You should base your work on it. It won't ever be
+   rebased or force-pushed to.
+
+ - `vx.y` branches exist to make patch releases on otherwise obsolete
+   minor releases. Should only contain fixes cherry picked from master.
+   Don't base any work on them.
+
+ - Other branches are probably topic branches and may be subject to
+   rebasing. Don't base any work on them unless you specifically know
+   otherwise.
+
+## Tags
+
+All releases are tagged semver style as `vx.y.z`. Release tags are
+signed by GPG key BCE524C7.

+ADVENTURE I. A SCANDAL IN BOHEMIA
+
+I.
+
+To Sherlock Holmes she is always THE woman. I have seldom heard
+him mention her under any other name. In his eyes she eclipses
+and predominates the whole of her sex. It was not that he felt
+any emotion akin to love for Irene Adler. All emotions, and that
+one particularly, were abhorrent to his cold, precise but
+admirably balanced mind. He was, I take it, the most perfect
+reasoning and observing machine that the world has seen, but as a
+lover he would have placed himself in a false position. He never
+spoke of the softer passions, save with a gibe and a sneer. They
+were admirable things for the observer--excellent for drawing the
+veil from men's motives and actions. But for the trained reasoner
+to admit such intrusions into his own delicate and finely
+adjusted temperament was to introduce a distracting factor which
+might throw a doubt upon all his mental results. Grit in a
+sensitive instrument, or a crack in one of his own high-power
+lenses, would not be more disturbing than a strong emotion in a
+nature such as his. And yet there was but one woman to him, and
+that woman was the late Irene Adler, of dubious and questionable
+memory.
+
+I had seen little of Holmes lately. My marriage had drifted us
+away from each other. My own complete happiness, and the
+home-centred interests which rise up around the man who first
+finds himself master of his own establishment, were sufficient to
+absorb all my attention, while Holmes, who loathed every form of
+society with his whole Bohemian soul, remained in our lodgings in
+Baker Street, buried among his old books, and alternating from
+week to week between cocaine and ambition, the drowsiness of the
+drug, and the fierce energy of his own keen nature. He was still,
+as ever, deeply attracted by the study of crime, and occupied his
+immense faculties and extraordinary powers of observation in
+following out those clues, and clearing up those mysteries which
+had been abandoned as hopeless by the official police. From time
+to time I heard some vague account of his doings: of his summons
+to Odessa in the case of the Trepoff murder, of his clearing up
+of the singular tragedy of the Atkinson brothers at Trincomalee,
+and finally of the mission which he had accomplished so
+delicately and successfully for the reigning family of Holland.
+Beyond these signs of his activity, however, which I merely
+shared with all the readers of the daily press, I knew little of
+my former friend and companion.

-===
-
-Yet another .INI file parser / writer. Created because the existing ones
-were either not general enough (allowing easy access to all parts of the
-original file) or made annoying assumptions about the format. And
-probably equal parts NIH. You might want to just write your own instead
-of using this one, you know that's where you'll end up in the end
-anyhow.
