 // line should be called before anything else:
 //
-// 	ctx := context.WithVersion(context.Background(), version)

-// Logging
+// # Logging
 //
 // The most useful aspect of this package is GetLogger. This function takes
 // any context.Context interface and returns the current logger from the
 // context. Canonical usage looks like this:
 //
-// 	GetLogger(ctx).Infof("something interesting happened")
+//	GetLogger(ctx).Infof("something interesting happened")
 //
 // GetLogger also takes optional key arguments. The keys will be looked up in
 // the context and reported with the logger. The following example would
 // return a logger that prints the version with each log message:
 //
-// 	ctx := context.Context(context.Background(), "version", version)
-// 	GetLogger(ctx, "version").Infof("this log message has a version field")
+//	ctx := context.Context(context.Background(), "version", version)
+//	GetLogger(ctx, "version").Infof("this log message has a version field")
 //
 // The above would print out a log message like this:
 //
-// 	INFO[0000] this log message has a version field        version=v2.0.0-alpha.2.m
+//	INFO[0000] this log message has a version field        version=v2.0.0-alpha.2.m
 //
 // When used with WithLogger, we gain the ability to decorate the context with
 // loggers that have information from disparate parts of the call stack.
 // Following from the version example, we can build a new context with the
 // configured logger such that we always print the version field:
 //
-// 	ctx = WithLogger(ctx, GetLogger(ctx, "version"))
+//	ctx = WithLogger(ctx, GetLogger(ctx, "version"))
 //
 // Since the logger has been pushed to the context, we can now get the version
 // field for free with our log messages. Future calls to GetLogger on the new
 // context will have the version field:
 //
-// 	GetLogger(ctx).Infof("this log message has a version field")
+//	GetLogger(ctx).Infof("this log message has a version field")
 //
 // This becomes more powerful when we start stacking loggers. Let's say we
 // have the version logger from above but also want a request id. Using the
 // context above, in our request scoped function, we place another logger in
 // the context:
 //
-// 	ctx = context.WithValue(ctx, "http.request.id", "unique id") // called when building request context
-// 	ctx = WithLogger(ctx, GetLogger(ctx, "http.request.id"))
+//	ctx = context.WithValue(ctx, "http.request.id", "unique id") // called when building request context
+//	ctx = WithLogger(ctx, GetLogger(ctx, "http.request.id"))
 //
 // When GetLogger is called on the new context, "http.request.id" will be
 // included as a logger field, along with the original "version" field:
 //
-// 	INFO[0000] this log message has a version field        http.request.id=unique id version=v2.0.0-alpha.2.m
+//	INFO[0000] this log message has a version field        http.request.id=unique id version=v2.0.0-alpha.2.m
 //
 // Note that this only affects the new context, the previous context, with the
 // version field, can be used independently. Put another way, the new logger,
 // added to the request context, is unique to that context and can have
 // request scoped variables.
 //
-// HTTP Requests
+// # HTTP Requests
 //
 // This package also contains several methods for working with http requests.
 // The concepts are very similar to those described above. We simply place the
 // request in the context using WithRequest. This makes the request variables
 // available. GetRequestLogger can then be called to get request specific
 // variables in a log line:
 //
-// 	ctx = WithRequest(ctx, req)
-// 	GetRequestLogger(ctx).Infof("request variables")
+//	ctx = WithRequest(ctx, req)
+//	GetRequestLogger(ctx).Infof("request variables")
 //
 // Like above, if we want to include the request data in all log messages in
 // the context, we push the logger to a new context and use that one:
 //
-// 	ctx = WithLogger(ctx, GetRequestLogger(ctx))
+//	ctx = WithLogger(ctx, GetRequestLogger(ctx))
