+# Contributor Code of Conduct
+
+This project adheres to [The Code Manifesto](http://codemanifesto.com)
+as its guidelines for contributor interactions.
+
+## The Code Manifesto
+
+We want to work in an ecosystem that empowers developers to reach their
+potential — one that encourages growth and effective collaboration. A space
+that is safe for all.
+
+A space such as this benefits everyone that participates in it. It encourages
+new developers to enter our field. It is through discussion and collaboration
+that we grow, and through growth that we improve.
+
+In the effort to create such a place, we hold to these values:
+
+1. **Discrimination limits us.** This includes discrimination on the basis of
+   race, gender, sexual orientation, gender identity, age, nationality,
+   technology and any other arbitrary exclusion of a group of people.
+2. **Boundaries honor us.** Your comfort levels are not everyone’s comfort
+   levels. Remember that, and if brought to your attention, heed it.
+3. **We are our biggest assets.** None of us were born masters of our trade.
+   Each of us has been helped along the way. Return that favor, when and where
+   you can.
+4. **We are resources for the future.** As an extension of #3, share what you
+   know. Make yourself a resource to help those that come after you.
+5. **Respect defines us.** Treat others as you wish to be treated. Make your
+   discussions, criticisms and debates from a position of respectfulness. Ask
+   yourself, is it true? Is it necessary? Is it constructive? Anything less is
+   unacceptable.
+6. **Reactions require grace.** Angry responses are valid, but abusive language
+   and vindictive actions are toxic. When something happens that offends you,
+   handle it assertively, but be respectful. Escalate reasonably, and try to
+   allow the offender an opportunity to explain themselves, and possibly
+   correct the issue.
+7. **Opinions are just that: opinions.** Each and every one of us, due to our
+   background and upbringing, have varying opinions. That is perfectly
+   acceptable. Remember this: if you respect your own opinions, you should
+   respect the opinions of others.
+8. **To err is human.** You might not intend it, but mistakes do happen and
+   contribute to build experience. Tolerate honest mistakes, and don't
+   hesitate to apologize if you make one yourself.

-An Implementation of BSON for Go
---------------------------------
-
-Package bson is an implementation of the [BSON specification](http://bsonspec.org) for Go.
-
-While the BSON package implements the BSON spec as faithfully as possible, there
-is some MongoDB specific behaviour (such as map keys `$in`, `$all`, etc) in the
-`bson` package. The priority is for backwards compatibility for the `mgo`
-driver, though fixes for obviously buggy behaviour is welcome (and features, etc
-behind feature flags).

 A foundational library to analyze an OAI specification document for easier reasoning about the content.
+
+## What's inside?
+
+* A analyzer providing methods to walk the functional content of a specification
+* A spec flattener producing a self-contained document bundle, while preserving `$ref`s
+* A spec merger ("mixin") to merge several spec documents into a primary spec
+* A spec "fixer" ensuring that response descriptions are non empty
+
+[Documentation](https://godoc.org/github.com/go-openapi/analysis)
+
+## FAQ
+
+* Does this library support OpenAPI 3?
+
+> No.
+> This package currently only supports OpenAPI 2.0 (aka Swagger 2.0).
+> There is no plan to make it evolve toward supporting OpenAPI 3.x.
+> This [discussion thread](https://github.com/go-openapi/spec/issues/21) relates the full story.
