+# OpenTelemetry Propagator AWS X-Ray
+
+[![NPM Published Version][npm-img]][npm-url]
+[![dependencies][dependencies-image]][dependencies-url]
+[![devDependencies][devDependencies-image]][devDependencies-url]
+[![Apache License][license-image]][license-image]
+
+The OpenTelemetry Propagator for AWS X-Ray provides HTTP header propagation for systems that are using AWS `X-Amzn-Trace-Id` format.
+This propagator translates the OpenTelemetry SpanContext into the equivalent AWS header format, for use with the OpenTelemetry JS SDK.
+`TraceState` is currently not propagated.
+
+### Installation
+
+```
+npm install --save @opentelemetry/propagator-aws-xray
+```
+
+### Usage
+
+In the [global tracer configuration file](https://github.com/open-telemetry/opentelemetry-js/blob/master/getting-started/README.md#initialize-a-global-tracer), configure the following:
+
+```js
+const { propagation } = require("@opentelemetry/api");
+const { AWSXRayPropagator } = require('@opentelemetry/propagator-aws-xray');
+// ...
+
+module.exports = ("service_name_here") => {
+ // set global propagator
+ propagation.setGlobalPropagator(new AWSXRayPropagator());
+ // ...}
+```
+
+### Propagator Details
+
+Example header:`X-Amzn-Trace-Id: Root=1-5759e988-bd862e3fe1be46a994272793;Parent=53995c3f42cd8ad8;Sampled=1`
+
+The header consists of three parts: the root trace ID, the parent ID and the sampling decision.
+
+#### Root - The AWS X-Ray format trace ID
+
+* Format: (spec-version)-(timestamp)-(UUID)
+ * spec_version - The version of the AWS X-Ray header format. Currently, only "1" is valid.
+ * timestamp - 32-bit number in base16 format, corresponds to the first 8 characters of the OpenTelemetry trace ID. Note, while X-Ray calls this timestamp, for the purpose of propagation it is opaque and any value will work.
+ * UUID - 96-bit random number in base16 format, corresponds to the last 10 characters of the OpenTelemetry trace ID.
+
+Root is analogous to the [OpenTelemetry Trace ID](https://github.com/open-telemetry/opentelemetry-specification/blob/master/specification/overview.md#spancontext), with some small format changes.
+For additional reading, see the [AWS X-Ray Trace ID](https://docs.aws.amazon.com/xray/latest/devguide/xray-api-sendingdata.html#xray-api-traceids) public documentation.
+
+#### Parent - The ID of the AWS X-Ray Segment
+
+* 64-bit random number in base16 format. Populated from the [OpenTelemetry Span ID](https://github.com/open-telemetry/opentelemetry-specification/blob/master/specification/overview.md#spancontext).
+
+#### Sampled - The sampling decision*
+
+* Defined in the AWS X-Ray specification as a tri-state field, with "0", "1" and "?" as valid values. Only "0" and "1" are used in this propagator. If "?", a new trace will be started.
+* Populated from the [OpenTelemetry trace flags](https://github.com/open-telemetry/opentelemetry-specification/blob/master/specification/overview.md#spancontext).
