+## Migration Guide from v2 -> v3
+
+Version 3 adds several new, frequently requested features.  To do so, it introduces a few breaking changes.  We've worked to keep these as minimal as possible.  This guide explains the breaking changes and how you can quickly update your code.
+
+### `Token.Claims` is now an interface type
+
+The most requested feature from the 2.0 verison of this library was the ability to provide a custom type to the JSON parser for claims. This was implemented by introducing a new interface, `Claims`, to replace `map[string]interface{}`.  We also included two concrete implementations of `Claims`: `MapClaims` and `StandardClaims`.
+
+`MapClaims` is an alias for `map[string]interface{}` with built in validation behavior.  It is the default claims type when using `Parse`.  The usage is unchanged except you must type cast the claims property.
+
+The old example for parsing a token looked like this..
+
+```go
+	if token, err := jwt.Parse(tokenString, keyLookupFunc); err == nil {
+		fmt.Printf("Token for user %v expires %v", token.Claims["user"], token.Claims["exp"])
+	}
+```
+
+is now directly mapped to...
+
+```go
+	if token, err := jwt.Parse(tokenString, keyLookupFunc); err == nil {
+		claims := token.Claims.(jwt.MapClaims)
+		fmt.Printf("Token for user %v expires %v", claims["user"], claims["exp"])
+	}
+```
+
+`StandardClaims` is designed to be embedded in your custom type.  You can supply a custom claims type with the new `ParseWithClaims` function.  Here's an example of using a custom claims type.
+
+```go
+	type MyCustomClaims struct {
+		User string
+		*StandardClaims
+	}
+	
+	if token, err := jwt.ParseWithClaims(tokenString, &MyCustomClaims{}, keyLookupFunc); err == nil {
+		claims := token.Claims.(*MyCustomClaims)
+		fmt.Printf("Token for user %v expires %v", claims.User, claims.StandardClaims.ExpiresAt)
+	}
+```
+
+### `ParseFromRequest` has been moved
+
+To keep this library focused on the tokens without becoming overburdened with complex request processing logic, `ParseFromRequest` and its new companion `ParseFromRequestWithClaims` have been moved to a subpackage, `request`.  The method signatues have also been augmented to receive a new argument: `Extractor`.
+
+`Extractors` do the work of picking the token string out of a request.  The interface is simple and composable.
+
+This simple parsing example:
+
+```go
+	if token, err := jwt.ParseFromRequest(tokenString, req, keyLookupFunc); err == nil {
+		fmt.Printf("Token for user %v expires %v", token.Claims["user"], token.Claims["exp"])
+	}
+```
+
+is directly mapped to:
+
+```go
+	if token, err := request.ParseFromRequest(tokenString, request.OAuth2Extractor, req, keyLookupFunc); err == nil {
+		fmt.Printf("Token for user %v expires %v", token.Claims["user"], token.Claims["exp"])
+	}
+```
+
+There are several concrete `Extractor` types provided for your convenience:
+
+* `HeaderExtractor` will search a list of headers until one contains content.
+* `ArgumentExtractor` will search a list of keys in request query and form arguments until one contains content.
+* `MultiExtractor` will try a list of `Extractors` in order until one returns content.
+* `AuthorizationHeaderExtractor` will look in the `Authorization` header for a `Bearer` token.
+* `OAuth2Extractor` searches the places an OAuth2 token would be specified (per the spec): `Authorization` header and `access_token` argument
+* `PostExtractionFilter` wraps an `Extractor`, allowing you to process the content before it's parsed.  A simple example is stripping the `Bearer ` text from a header
+
+
+### RSA signing methods no longer accept `[]byte` keys
+
+Due to a [critical vulnerability](https://auth0.com/blog/2015/03/31/critical-vulnerabilities-in-json-web-token-libraries/), we've decided the convenience of accepting `[]byte` instead of `rsa.PublicKey` or `rsa.PrivateKey` isn't worth the risk of misuse.
+
+To replace this behavior, we've added two helper methods: `ParseRSAPrivateKeyFromPEM(key []byte) (*rsa.PrivateKey, error)` and `ParseRSAPublicKeyFromPEM(key []byte) (*rsa.PublicKey, error)`.  These are just simple helpers for unpacking PEM encoded PKCS1 and PKCS8 keys. If your keys are encoded any other way, all you need to do is convert them to the `crypto/rsa` package's types.
+
+```go 
+	func keyLookupFunc(*Token) (interface{}, error) {
+		// Don't forget to validate the alg is what you expect:
+		if _, ok := token.Method.(*jwt.SigningMethodRSA); !ok {
+			return nil, fmt.Errorf("Unexpected signing method: %v", token.Header["alg"])
+		}
+		
+		// Look up key 
+		key, err := lookupPublicKey(token.Header["kid"])
+		if err != nil {
+			return nil, err
+		}
+		
+		// Unpack key from PEM encoded PKCS8
+		return jwt.ParseRSAPublicKeyFromPEM(key)
+	}
+```

+
+[![Build Status](https://travis-ci.org/dgrijalva/jwt-go.svg?branch=master)](https://travis-ci.org/dgrijalva/jwt-go)
+
+**BREAKING CHANGES:*** Version 3.0.0 is here. It includes _a lot_ of changes including a few that break the API.  We've tried to break as few things as possible, so there should just be a few type signature changes.  A full list of breaking changes is available in `VERSION_HISTORY.md`.  See `MIGRATION_GUIDE.md` for more information on updating your code.
+
+**NOTICE:** A vulnerability in JWT was [recently published](https://auth0.com/blog/2015/03/31/critical-vulnerabilities-in-json-web-token-libraries/).  As this library doesn't force users to validate the `alg` is what they expected, it's possible your usage is effected.  There will be an update soon to remedy this, and it will likey require backwards-incompatible changes to the API.  In the short term, please make sure your implementation verifies the `alg` is what you expect.
+
+
+## What the heck is a JWT?
+
+JWT.io has [a great introduction](https://jwt.io/introduction) to JSON Web Tokens.
+
+In short, it's a signed JSON object that does something useful (for example, authentication).  It's commonly used for `Bearer` tokens in Oauth 2.  A token is made of three parts, separated by `.`'s.  The first two parts are JSON objects, that have been [base64url](http://tools.ietf.org/html/rfc4648) encoded.  The last part is the signature, encoded the same way.
+
+The first part is called the header.  It contains the necessary information for verifying the last part, the signature.  For example, which encryption method was used for signing and what key was used.
+
+The part in the middle is the interesting bit.  It's called the Claims and contains the actual stuff you care about.  Refer to [the RFC](http://self-issued.info/docs/draft-jones-json-web-token.html) for information about reserved keys and the proper way to add your own.
+
+## What's in the box?
+
+This library supports the parsing and verification as well as the generation and signing of JWTs.  Current supported signing algorithms are HMAC SHA, RSA, RSA-PSS, and ECDSA, though hooks are present for adding your own.
+
+## Examples
+
+See [the project documentation](https://godoc.org/github.com/dgrijalva/jwt-go) for examples of usage:
+
+* [Simple example of parsing and validating a token](https://godoc.org/github.com/dgrijalva/jwt-go#example-Parse--Hmac)
+* [Simple example of building and signing a token](https://godoc.org/github.com/dgrijalva/jwt-go#example-New--Hmac)
+* [Directory of Examples](https://godoc.org/github.com/dgrijalva/jwt-go#pkg-examples)
+
+## Extensions
+
+This library publishes all the necessary components for adding your own signing methods.  Simply implement the `SigningMethod` interface and register a factory method using `RegisterSigningMethod`.  
+
+Here's an example of an extension that integrates with the Google App Engine signing tools: https://github.com/someone1/gcp-jwt-go
+
+## Compliance
+
+This library was last reviewed to comply with [RTF 7519](http://www.rfc-editor.org/info/rfc7519) dated May 2015 with a few notable differences: 
+
+* In order to protect against accidental use of [Unsecured JWTs](http://self-issued.info/docs/draft-ietf-oauth-json-web-token.html#UnsecuredJWT), tokens using `alg=none` will only be accepted if the constant `jwt.UnsafeAllowNoneSignatureType` is provided as the key.
+
+## Project Status & Versioning
+
+This library is considered production ready.  Feedback and feature requests are appreciated.  The API should be considered stable.  There should be very few backwards-incompatible changes outside of major version updates (and only with good reason).
+
+This project uses [Semantic Versioning 2.0.0](http://semver.org).  Accepted pull requests will land on `master`.  Periodically, versions will be tagged from `master`.  You can find all the releases on [the project releases page](https://github.com/dgrijalva/jwt-go/releases).
+
+While we try to make it obvious when we make breaking changes, there isn't a great mechanism for pushing announcements out to users.  You may want to use this alternative package include: `gopkg.in/dgrijalva/jwt-go.v2`.  It will do the right thing WRT semantic versioning.
+
+## Usage Tips
+
+### Signing vs Encryption
+
+A token is simply a JSON object that is signed by its author. this tells you exactly two things about the data:
+
+* The author of the token was in the possession of the signing secret
+* The data has not been modified since it was signed
+
+It's important to know that JWT does not provide encryption, which means anyone who has access to the token can read its contents. If you need to protect (encrypt) the data, there is a companion spec, `JWE`, that provides this functionality. JWE is currently outside the scope of this library.
+
+### Choosing a Signing Method
+
+There are several signing methods available, and you should probably take the time to learn about the various options before choosing one.  The principal design decision is most likely going to be symmetric vs asymmetric.
+
+Symmetric signing methods, such as HSA, use only a single secret. This is probably the simplest signing method to use since any `[]byte` can be used as a valid secret. They are also slightly computationally faster to use, though this rarely is enough to matter. Symmetric signing methods work the best when both producers and consumers of tokens are trusted, or even the same system. Since the same secret is used to both sign and validate tokens, you can't easily distribute the key for validation.
+
+Asymmetric signing methods, such as RSA, use different keys for signing and verifying tokens. This makes it possible to produce tokens with a private key, and allow any consumer to access the public key for verification.
+
+### JWT and OAuth
+
+It's worth mentioning that OAuth and JWT are not the same thing. A JWT token is simply a signed JSON object. It can be used anywhere such a thing is useful. There is some confusion, though, as JWT is the most common type of bearer token used in OAuth2 authentication.
+
+Without going too far down the rabbit hole, here's a description of the interaction of these technologies:
+
+* OAuth is a protocol for allowing an identity provider to be separate from the service a user is logging in to.  For example, whenever you use Facebook to log into a different service (Yelp, Spotify, etc), you are using OAuth.
+* OAuth defines several options for passing around authentication data. One popular method is called a "bearer token". A bearer token is simply a string that _should_ only be held by an authenticated user. Thus, simply presenting this token proves your identity. You can probably derive from here why a JWT might make a good bearer token.
+* Because bearer tokens are used for authentication, it's important they're kept secret. This is why transactions that use bearer tokens typically happen over SSL.
+ 
+## More
+
+Documentation can be found [on godoc.org](http://godoc.org/github.com/dgrijalva/jwt-go).
+
+The command line utility included in this project (cmd/jwt) provides a straightforward example of token creation and parsing as well as a useful tool for debugging your own integration.  You'll also find several implementation examples in to documentation.

+## `jwt-go` Version History
+
+#### 3.0.0
+
+* **Compatibility Breaking Changes**: See MIGRATION_GUIDE.md for tips on updating your code
+	* Dropped support for `[]byte` keys when using RSA signing methods.  This convenience feature could contribute to security vulnerabilities involving mismatched key types with signing methods.
+	* `ParseFromRequest` has been moved to `request` subpackage and usage has changed
+	* The `Claims` property on `Token` is now type `Claims` instead of `map[string]interface{}`.  The default value is type `MapClaims`, which is an alias to `map[string]interface{}`.  This makes it possible to use a custom type when decoding claims.
+* Other Additions and Changes
+	* Added `Claims` interface type to allow users to decode the claims into a custom type
+	* Added `ParseWithClaims`, which takes a third argument of type `Claims`.  Use this function instead of `Parse` if you have a custom type you'd like to decode into.
+	* Dramatically improved the functionality and flexibility of `ParseFromRequest`, which is now in the `request` subpackage
+	* Added `ParseFromRequestWithClaims` which is the `FromRequest` equivalent of `ParseWithClaims`
+	* Added new interface type `Extractor`, which is used for extracting JWT strings from http requests.  Used with `ParseFromRequest` and `ParseFromRequestWithClaims`.
+	* Added several new, more specific, validation errors to error type bitmask
+	* Moved examples from README to executable example files
+	* Signing method registry is now thread safe
+	* Added new property to `ValidationError`, which contains the raw error returned by calls made by parse/verify (such as those returned by keyfunc or json parser)
+
+#### 2.7.0
+
+This will likely be the last backwards compatible release before 3.0.0, excluding essential bug fixes.
+
+* Added new option `-show` to the `jwt` command that will just output the decoded token without verifying
+* Error text for expired tokens includes how long it's been expired
+* Fixed incorrect error returned from `ParseRSAPublicKeyFromPEM`
+* Documentation updates
+
+#### 2.6.0
+
+* Exposed inner error within ValidationError
+* Fixed validation errors when using UseJSONNumber flag
+* Added several unit tests
+
+#### 2.5.0
+
+* Added support for signing method none.  You shouldn't use this.  The API tries to make this clear.
+* Updated/fixed some documentation
+* Added more helpful error message when trying to parse tokens that begin with `BEARER `
+
+#### 2.4.0
+
+* Added new type, Parser, to allow for configuration of various parsing parameters
+	* You can now specify a list of valid signing methods.  Anything outside this set will be rejected.
+	* You can now opt to use the `json.Number` type instead of `float64` when parsing token JSON
+* Added support for [Travis CI](https://travis-ci.org/dgrijalva/jwt-go)
+* Fixed some bugs with ECDSA parsing
+
+#### 2.3.0
+
+* Added support for ECDSA signing methods
+* Added support for RSA PSS signing methods (requires go v1.4)
+
+#### 2.2.0
+
+* Gracefully handle a `nil` `Keyfunc` being passed to `Parse`.  Result will now be the parsed token and an error, instead of a panic.
+
+#### 2.1.0
+
+Backwards compatible API change that was missed in 2.0.0.
+
+* The `SignedString` method on `Token` now takes `interface{}` instead of `[]byte`
+
+#### 2.0.0
+
+There were two major reasons for breaking backwards compatibility with this update.  The first was a refactor required to expand the width of the RSA and HMAC-SHA signing implementations.  There will likely be no required code changes to support this change.
+
+The second update, while unfortunately requiring a small change in integration, is required to open up this library to other signing methods.  Not all keys used for all signing methods have a single standard on-disk representation.  Requiring `[]byte` as the type for all keys proved too limiting.  Additionally, this implementation allows for pre-parsed tokens to be reused, which might matter in an application that parses a high volume of tokens with a small set of keys.  Backwards compatibilty has been maintained for passing `[]byte` to the RSA signing methods, but they will also accept `*rsa.PublicKey` and `*rsa.PrivateKey`.
+
+It is likely the only integration change required here will be to change `func(t *jwt.Token) ([]byte, error)` to `func(t *jwt.Token) (interface{}, error)` when calling `Parse`.
+
+* **Compatibility Breaking Changes**
+	* `SigningMethodHS256` is now `*SigningMethodHMAC` instead of `type struct`
+	* `SigningMethodRS256` is now `*SigningMethodRSA` instead of `type struct`
+	* `KeyFunc` now returns `interface{}` instead of `[]byte`
+	* `SigningMethod.Sign` now takes `interface{}` instead of `[]byte` for the key
+	* `SigningMethod.Verify` now takes `interface{}` instead of `[]byte` for the key
+* Renamed type `SigningMethodHS256` to `SigningMethodHMAC`.  Specific sizes are now just instances of this type.
+    * Added public package global `SigningMethodHS256`
+    * Added public package global `SigningMethodHS384`
+    * Added public package global `SigningMethodHS512`
+* Renamed type `SigningMethodRS256` to `SigningMethodRSA`.  Specific sizes are now just instances of this type.
+    * Added public package global `SigningMethodRS256`
+    * Added public package global `SigningMethodRS384`
+    * Added public package global `SigningMethodRS512`
+* Moved sample private key for HMAC tests from an inline value to a file on disk.  Value is unchanged.
+* Refactored the RSA implementation to be easier to read
+* Exposed helper methods `ParseRSAPrivateKeyFromPEM` and `ParseRSAPublicKeyFromPEM`
+
+#### 1.0.2
+
+* Fixed bug in parsing public keys from certificates
+* Added more tests around the parsing of keys for RS256
+* Code refactoring in RS256 implementation.  No functional changes
+
+#### 1.0.1
+
+* Fixed panic if RS256 signing method was passed an invalid key
+
+#### 1.0.0
+
+* First versioned release
+* API stabilized
+* Supports creating, signing, parsing, and validating JWT tokens
+* Supports RS256 and HS256 signing methods

+
+**Go kit** is a **distributed programming toolkit** for building microservices
+in large organizations. We solve common problems in distributed systems, so
+you can focus on your business logic.
+
+- Website: [gokit.io](https://gokit.io)
+- Mailing list: [go-kit](https://groups.google.com/forum/#!forum/go-kit)
+- Slack: [gophers.slack.com](https://gophers.slack.com) **#go-kit** ([invite](https://gophersinvite.herokuapp.com/))
+
+## Motivation
+
+Go has emerged as the language of the server, but it remains underrepresented
+in large, consumer-focused tech companies like Facebook, Twitter, Netflix, and
+SoundCloud. These organizations have largely adopted JVM-based stacks for
+their business logic, owing in large part to libraries and ecosystems that
+directly support their microservice architectures.
+
+To reach its next level of success, Go needs more than simple primitives and
+idioms. It needs a comprehensive toolkit, for coherent distributed programming
+in the large. Go kit is a set of packages and best practices, which provide a
+comprehensive, robust, and trustable way of building microservices for
+organizations of any size.
+
+For more details, see
+ [the website](https://gokit.io),
+ [the motivating blog post](http://peter.bourgon.org/go-kit/) and
+ [the video of the talk](https://www.youtube.com/watch?v=iFR_7AKkJFU).
+See also the
+ [Go kit talk at GopherCon 2015](https://www.youtube.com/watch?v=1AjaZi4QuGo).
+
+## Goals
+
+- Operate in a heterogeneous SOA — expect to interact with mostly non-Go-kit services
+- RPC as the primary messaging pattern
+- Pluggable serialization and transport — not just JSON over HTTP
+- Operate within existing infrastructures — no mandates for specific tools or technologies
+
+## Non-goals
+
+- Supporting messaging patterns other than RPC (for now) — e.g. MPI, pub/sub, CQRS, etc.
+- Re-implementing functionality that can be provided by adapting existing software
+- Having opinions on operational concerns: deployment, configuration, process supervision, orchestration, etc.
+
+## Contributing
+
+Please see [CONTRIBUTING.md](/CONTRIBUTING.md).
+Thank you, [contributors](https://github.com/go-kit/kit/graphs/contributors)!
+
+## Dependency management
+
+Go kit is a library, designed to be imported into a binary package.
+Vendoring is currently the best way for binary package authors
+ to ensure reliable, reproducible builds.
+Therefore, we strongly recommend our users use vendoring for all of their dependencies,
+ including Go kit.
+To avoid compatibility and availability issues,
+ Go kit doesn't vendor its own dependencies,
+ and doesn't recommend use of third-party import proxies.
+
+There are several tools which make vendoring easier, including
+ [gb](http://getgb.io),
+ [glide](https://github.com/Masterminds/glide),
+ [gvt](https://github.com/FiloSottile/gvt),
+ [govendor](https://github.com/kardianos/govendor), and
+ [vendetta](https://github.com/dpw/vendetta).
+In addition, Go kit uses a variety of continuous integration providers
+ to find and fix compatibility problems as soon as they occur.

+# package auth/jwt
+
+`package auth/jwt` provides a set of interfaces for service authorization
+through [JSON Web Tokens](https://jwt.io/).
+
+## Usage
+
+NewParser takes a key function and an expected signing method and returns an
+`endpoint.Middleware`. The middleware will parse a token passed into the
+context via the `jwt.JWTTokenContextKey`. If the token is valid, any claims
+will be added to the context via the `jwt.JWTClaimsContextKey`.
+
+```go
+import (
+	stdjwt "github.com/dgrijalva/jwt-go"
+	
+	"github.com/go-kit/kit/auth/jwt"
+	"github.com/go-kit/kit/endpoint"
+)
+
+func main() {
+	var exampleEndpoint endpoint.Endpoint
+	{
+		kf := func(token *stdjwt.Token) (interface{}, error) { return []byte("SigningString"), nil }
+		exampleEndpoint = MakeExampleEndpoint(service)
+		exampleEndpoint = jwt.NewParser(kf, stdjwt.SigningMethodHS256)(exampleEndpoint)
+	}
+}
+```
+
+NewSigner takes a JWT key ID header, the signing key, signing method, and a
+claims object. It returns an `endpoint.Middleware`. The middleware will build
+the token string and add it to the context via the `jwt.JWTTokenContextKey`.
+
+```go
+import (
+	stdjwt "github.com/dgrijalva/jwt-go"
+	
+	"github.com/go-kit/kit/auth/jwt"
+	"github.com/go-kit/kit/endpoint"
+)
+
+func main() {
+	var exampleEndpoint endpoint.Endpoint
+	{
+		exampleEndpoint = grpctransport.NewClient(...).Endpoint()
+		exampleEndpoint = jwt.NewSigner(
+			"kid-header", 
+			[]byte("SigningString"), 
+			stdjwt.SigningMethodHS256, 
+			jwt.Claims{},
+		)(exampleEndpoint)
+	}
+}
+```
+
+In order for the parser and the signer to work, the authorization headers need
+to be passed between the request and the context. `ToHTTPContext()`,
+`FromHTTPContext()`, `ToGRPCContext()`, and `FromGRPCContext()` are given as
+helpers to do this. These functions implement the correlating transport's
+RequestFunc interface and can be passed as ClientBefore or ServerBefore
+options.
+
+Example of use in a client:
+
+```go
+import (
+	stdjwt "github.com/dgrijalva/jwt-go"
+
+	grpctransport "github.com/go-kit/kit/transport/grpc"	
+	"github.com/go-kit/kit/auth/jwt"
+	"github.com/go-kit/kit/endpoint"
+)
+
+func main() {
+
+	options := []httptransport.ClientOption{}
+	var exampleEndpoint endpoint.Endpoint
+	{
+		exampleEndpoint = grpctransport.NewClient(..., grpctransport.ClientBefore(jwt.FromGRPCContext())).Endpoint()
+		exampleEndpoint = jwt.NewSigner(
+			"kid-header",
+			[]byte("SigningString"),
+			stdjwt.SigningMethodHS256,
+			jwt.Claims{},
+		)(exampleEndpoint)
+	}
+}
+```
+
+Example of use in a server:
+
+```go
+import (
+	"golang.org/x/net/context"
+
+	"github.com/go-kit/kit/auth/jwt"
+	"github.com/go-kit/kit/log"
+	grpctransport "github.com/go-kit/kit/transport/grpc"
+)
+
+func MakeGRPCServer(ctx context.Context, endpoints Endpoints, logger log.Logger) pb.ExampleServer {
+	options := []grpctransport.ServerOption{grpctransport.ServerErrorLogger(logger)}
+
+	return &grpcServer{
+		createUser: grpctransport.NewServer(
+			ctx,
+			endpoints.CreateUserEndpoint,
+			DecodeGRPCCreateUserRequest,
+			EncodeGRPCCreateUserResponse,
+			append(options, grpctransport.ServerBefore(jwt.ToGRPCContext()))...,
+		),
+		getUser: grpctransport.NewServer(
+			ctx,
+			endpoints.GetUserEndpoint,
+			DecodeGRPCGetUserRequest,
+			EncodeGRPCGetUserResponse,
+			options...,

+# package log
+
+`package log` provides a minimal interface for structured logging in services.
+It may be wrapped to encode conventions, enforce type-safety, provide leveled logging, and so on.
+It can be used for both typical application log events, and log-structured data streams.
+
+## Structured logging
+
+Structured logging is, basically, conceding to the reality that logs are _data_,
+ and warrant some level of schematic rigor.
+Using a stricter, key/value-oriented message format for our logs,
+ containing contextual and semantic information,
+ makes it much easier to get insight into the operational activity of the systems we build.
+Consequently, `package log` is of the strong belief that
+ "[the benefits of structured logging outweigh the minimal effort involved](https://www.thoughtworks.com/radar/techniques/structured-logging)".
+
+Migrating from unstructured to structured logging is probably a lot easier than you'd expect.
+
+```go
+// Unstructured
+log.Printf("HTTP server listening on %s", addr)
+
+// Structured
+logger.Log("transport", "HTTP", "addr", addr, "msg", "listening")
+```
+
+## Usage
+
+### Typical application logging
+
+```go
+w := log.NewSyncWriter(os.Stderr)
+logger := log.NewLogfmtLogger(w)
+logger.Log("question", "what is the meaning of life?", "answer", 42)
+
+// Output:
+// question="what is the meaning of life?" answer=42
+```
+
+### Log contexts
+
+```go
+func main() {
+	var logger log.Logger
+	logger = log.NewLogfmtLogger(log.NewSyncWriter(os.Stderr))
+	logger = log.NewContext(logger).With("instance_id", 123)
+
+	logger.Log("msg", "starting")
+	NewWorker(log.NewContext(logger).With("component", "worker")).Run()
+	NewSlacker(log.NewContext(logger).With("component", "slacker")).Run()
+}
+
+// Output:
+// instance_id=123 msg=starting
+// instance_id=123 component=worker msg=running
+// instance_id=123 component=slacker msg=running
+```
+
+### Interact with stdlib logger
+
+Redirect stdlib logger to Go kit logger.
+
+```go
+import (
+	"os"
+	stdlog "log"
+	kitlog "github.com/go-kit/kit/log"
+)
+
+func main() {
+	logger := kitlog.NewJSONLogger(kitlog.NewSyncWriter(os.Stdout))
+	stdlog.SetOutput(kitlog.NewStdlibAdapter(logger))
+	stdlog.Print("I sure like pie")
+}
+
+// Output:
+// {"msg":"I sure like pie","ts":"2016/01/01 12:34:56"}
+```
+
+Or, if, for legacy reasons,
+ you need to pipe all of your logging through the stdlib log package,
+ you can redirect Go kit logger to the stdlib logger.
+
+```go
+logger := kitlog.NewLogfmtLogger(kitlog.StdlibWriter{})
+logger.Log("legacy", true, "msg", "at least it's something")
+
+// Output:
+// 2016/01/01 12:34:56 legacy=true msg="at least it's something"
+```
+
+### Timestamps and callers
+
+```go
+var logger log.Logger
+logger = log.NewLogfmtLogger(log.NewSyncWriter(os.Stderr))
+logger = log.NewContext(logger).With("ts", log.DefaultTimestampUTC, "caller", log.DefaultCaller)
+
+logger.Log("msg", "hello")
+
+// Output:
+// ts=2016-01-01T12:34:56Z caller=main.go:15 msg=hello
+```
+
+## Supported output formats
+
+- [Logfmt](https://brandur.org/logfmt)
+- JSON
+
+## Enhancements
+
+`package log` is centered on the one-method Logger interface.
+
+```go
+type Logger interface {
+	Log(keyvals ...interface{}) error
+}
+```
+
+This interface, and its supporting code like [log.Context](https://godoc.org/github.com/go-kit/kit/log#Context),
+ is the product of much iteration and evaluation.
+For more details on the evolution of the Logger interface,
+ see [The Hunt for a Logger Interface](http://go-talks.appspot.com/github.com/ChrisHines/talks/structured-logging/structured-logging.slide#1),
+ a talk by [Chris Hines](https://github.com/ChrisHines).
+Also, please see
+ [#63](https://github.com/go-kit/kit/issues/63),
+ [#76](https://github.com/go-kit/kit/pull/76),
+ [#131](https://github.com/go-kit/kit/issues/131),
+ [#157](https://github.com/go-kit/kit/pull/157),
+ [#164](https://github.com/go-kit/kit/issues/164), and
+ [#252](https://github.com/go-kit/kit/pull/252)
+ to review historical conversations about package log and the Logger interface.
+
+Value-add packages and suggestions,
+ like improvements to [the leveled logger](https://godoc.org/github.com/go-kit/kit/log/levels),
+ are of course welcome.
+Good proposals should
+
+- Be composable with [log.Context](https://godoc.org/github.com/go-kit/kit/log#Context),
+- Not break the behavior of [log.Caller](https://godoc.org/github.com/go-kit/kit/log#Caller) in any wrapped context, and
+- Be friendly to packages that accept only an unadorned log.Logger.
+
+## Benchmarks & comparisons
+
+There are a few Go logging benchmarks and comparisons that include Go kit's package log.
+
+- [imkira/go-loggers-bench](https://github.com/imkira/go-loggers-bench) includes kit/log
+- [uber-common/zap](https://github.com/uber-common/zap), a zero-alloc logging library, includes a comparison with kit/log

+// Package log provides a structured logger.
+//
+// Structured logging produces logs easily consumed later by humans or
+// machines. Humans might be interested in debugging errors, or tracing
+// specific requests. Machines might be interested in counting interesting
+// events, or aggregating information for off-line processing. In both cases,
+// it is important that the log messages are structured and actionable.
+// Package log is designed to encourage both of these best practices.
+//
+// Basic Usage
+//
+// The fundamental interface is Logger. Loggers create log events from
+// key/value data. The Logger interface has a single method, Log, which
+// accepts a sequence of alternating key/value pairs, which this package names
+// keyvals.
+//
+//    type Logger interface {
+//        Log(keyvals ...interface{}) error
+//    }
+//
+// Here is an example of a function using a Logger to create log events.
+//
+//    func RunTask(task Task, logger log.Logger) string {
+//        logger.Log("taskID", task.ID, "event", "starting task")
+//        ...
+//        logger.Log("taskID", task.ID, "event", "task complete")
+//    }
+//
+// The keys in the above example are "taskID" and "event". The values are
+// task.ID, "starting task", and "task complete". Every key is followed
+// immediately by its value.
+//
+// Keys are usually plain strings. Values may be any type that has a sensible
+// encoding in the chosen log format. With structured logging it is a good
+// idea to log simple values without formatting them. This practice allows
+// the chosen logger to encode values in the most appropriate way.
+//
+// Log Context
+//
+// A log context stores keyvals that it includes in all log events. Building
+// appropriate log contexts reduces repetition and aids consistency in the
+// resulting log output. We can use a context to improve the RunTask example.
+//
+//    func RunTask(task Task, logger log.Logger) string {
+//        logger = log.NewContext(logger).With("taskID", task.ID)
+//        logger.Log("event", "starting task")
+//        ...
+//        taskHelper(task.Cmd, logger)
+//        ...
+//        logger.Log("event", "task complete")
+//    }
+//
+// The improved version emits the same log events as the original for the
+// first and last calls to Log. The call to taskHelper highlights that a
+// context may be passed as a logger to other functions. Each log event
+// created by the called function will include the task.ID even though the
+// function does not have access to that value. Using log contexts this way
+// simplifies producing log output that enables tracing the life cycle of
+// individual tasks. (See the Context example for the full code of the
+// above snippet.)
+//
+// Dynamic Context Values
+//
+// A Valuer function stored in a log context generates a new value each time
+// the context logs an event. The Valuer example demonstrates how this
+// feature works.
+//
+// Valuers provide the basis for consistently logging timestamps and source
+// code location. The log package defines several valuers for that purpose.
+// See Timestamp, DefaultTimestamp, DefaultTimestampUTC, Caller, and
+// DefaultCaller. A common logger initialization sequence that ensures all log
+// entries contain a timestamp and source location looks like this:
+//
+//    logger := log.NewLogfmtLogger(log.NewSyncWriter(os.Stdout))
+//    logger = log.NewContext(logger).With("ts", log.DefaultTimestampUTC, "caller", log.DefaultCaller)
+//
+// Concurrent Safety
+//
+// Applications with multiple goroutines want each log event written to the
+// same logger to remain separate from other log events. Package log provides
+// two simple solutions for concurrent safe logging.
+//
+// NewSyncWriter wraps an io.Writer and serializes each call to its Write
+// method. Using a SyncWriter has the benefit that the smallest practical
+// portion of the logging logic is performed within a mutex, but it requires
+// the formatting Logger to make only one call to Write per log event.
+//
+// NewSyncLogger wraps any Logger and serializes each call to its Log method.
+// Using a SyncLogger has the benefit that it guarantees each log event is
+// handled atomically within the wrapped logger, but it typically serializes
+// both the formatting and output logic. Use a SyncLogger if the formatting
+// logger may perform multiple writes per log event.

+// calling a value method through a pointer variable. These wrapper methods
+// are also used when calling a value method through an interface variable
+// because interfaces store a pointer to the underlying concrete value.
+// Calling a pointer receiver through an interface does not require generating
+// an additional function.
+//
+// If Context had value methods then calling Context.Log through a variable
+// with type Logger would have an extra stack frame compared to calling
+// Context.Log through a variable with type Context. Using pointer receivers
+// avoids this problem.
+
+// A Context wraps a Logger and holds keyvals that it includes in all log
+// events. When logging, a Context replaces all value elements (odd indexes)
+// containing a Valuer with their generated value for each call to its Log
+// method.
