-- [x] ~~Publish spans in a separate goroutine~~
-- [x] ~~Support propagation of http spans~~
-- [x] ~~Support remote spans~~
-- [x] ~~Verified works with ELB/ALB~~
-- [x] ~~Report errors / exceptions~~
-- [x] ~~Publish partial segments; currently only completed segments are published to aws~~
+## Quick Start
+
+If your app is running inside AWS, the simplest way to use the Amazon exporter is:
+
+```go
+exporter, _ := aws.NewExporter()
+trace.RegisterExporter(exporter)
+```
+
+If you're outside AWS, you'll need to make sure to configure the AWS credentials along
+with the aws region where the traces should be published.  The simplest way to do this
+is by setting the following environment variables:
+
+* `AWS_ACCESS_KEY_ID` 
+* `AWS_SECRET_ACCESS_KEY` 
+* `AWS_DEFAULT_REGION` 
+
+## Big Caveat
+
+Currently, Amazon X-Ray TraceID's are incompatible with OpenCensus TraceIDs.  Consequently,
+you must construct a valid TraceID and use http propagation.  
+
+Fortunately, if you're running in AWS behind an `ELB` or `ALB`, the load balancer will
+provide the necessary `X-Amzn-Trace-Id` header.  You can simply wrap your handler with
+`ochttp.Handler` 
+
+```go
+h := &ochttp.Handler{
+    Propagation: &aws.HTTPFormat{},
+    Handler:     handler,
+}
+```   
+
+The downside is if you're not running AWS e.g. your local desktop, getting traces is a pain 
+for now.
+
+## Credentials
+
+The Amazon exporter uses `github.com/aws/aws-sdk-go` and so supports the common methods
+for configuring credentials:
+
+* Environment variables, `AWS_ACCESS_KEY_ID` and `AWS_SECRET_ACCESS_KEY`
+* Shared credentials,  `~/.aws/credentials`
+* Role credentials: EC2, ECS, Lambda, etc
+
+## Region
+
+The Amazon exporter requires the aws region where traces will be set to be defined.  The
+following methods are provided:
+
+* Environment variable, `AWS_DEFAULT_REGION` or `AWS_REGION`
+* Explicitly via the `WithRegion` option e.g. `aws.NewExporter(aws.WithRegion("us-west-2"))`
+
+If neither of these are specified, the Amazon exporter will attempt to query the aws
+metadata url, `http://169.254.169.254/latest/meta-data/placement/availability-zone`, and
+publish traces to the current region.
