+We recommended using a dependency manager like [dep](https://golang.github.io/dep/)
 and [semantic versioning](http://semver.org/) when including this library into an application.
 For example, Jaeger backend imports this library like this:
 
-```yaml

-  version: ^2.7.0

+[[constraint]]
+  name = "github.com/uber/jaeger-client-go"

 ```
 
 If you instead want to use the latest version in `master`, you can pull it via `go get`.
 Note that during `go get` you may see build errors due to incompatible dependencies, which is why
 we recommend using semantic versions for dependencies.  The error  may be fixed by running

+## SelfRef
+
+Jaeger Tracer supports an additional [reference](https://github.com/opentracing/specification/blob/1.1/specification.md#references-between-spans)
+type call `Self`. This allows a caller to provide an already established `SpanContext`.
+This allows loading and continuing spans/traces from offline (ie log-based) storage. The `Self` reference
+bypasses trace and span id generation.
+
+
+Usage requires passing in a `SpanContext` and the jaeger `Self` reference type:
+```
+span := tracer.StartSpan(
+    "continued_span",
+    SelfRef(yourSpanContext),
+)
+...
+defer span.finish()
