+# OpenTelemetry Zipkin Trace Exporter
+
+[![NPM Published Version][npm-img]][npm-url]
+[![Apache License][license-image]][license-image]
+
+OpenTelemetry Zipkin Trace Exporter allows the user to send collected traces to Zipkin.
+
+[Zipkin](https://zipkin.io/) is a distributed tracing system. It helps gather timing data needed to troubleshoot latency problems in microservice architectures. It manages both the collection and lookup of this data.
+
+## Installation
+
+```bash
+npm install --save @opentelemetry/exporter-zipkin
+```
+
+## Usage in Node and Browser
+
+Install the exporter on your application and pass the options. `serviceName` is an optional string. If omitted, the exporter will first try to get the service name from the Resource. If no service name can be detected on the Resource, a fallback name of "OpenTelemetry Service" will be used.
+
+```js
+const { ZipkinExporter } = require('@opentelemetry/exporter-zipkin');
+
+// Add your zipkin url (`http://localhost:9411/api/v2/spans` is used as
+// default) and application name to the Zipkin options.
+// You can also define your custom headers which will be added automatically.
+const options = {
+  headers: {
+    'my-header': 'header-value',
+  },
+  url: 'your-zipkin-url',
+  // optional interceptor
+  getExportRequestHeaders: () => {
+    return {
+      'my-header': 'header-value',
+    }
+  }
+}
+const exporter = new ZipkinExporter(options);
+```
+
+Now, register the exporter and start tracing.
+
+```js
+const tracerProvider = new NodeTracerProvider({
+  spanProcessors: [new BatchSpanProcessor(exporter)]
+})
+
+const tracer = traceProvider.getTracer('my-tracer')
+```
+
+You can use built-in `SimpleSpanProcessor` or `BatchSpanProcessor` or write your own.
+
+- [SimpleSpanProcessor](https://github.com/open-telemetry/opentelemetry-specification/blob/master/specification/trace/sdk.md#simple-processor): The implementation of `SpanProcessor` that passes ended span directly to the configured `SpanExporter`.
+- [BatchSpanProcessor](https://github.com/open-telemetry/opentelemetry-specification/blob/master/specification/trace/sdk.md#batching-processor): The implementation of the `SpanProcessor` that batches ended spans and pushes them to the configured `SpanExporter`. It is recommended to use this `SpanProcessor` for better performance and optimization.
+
+### Options
+
+- **getExportRequestHeaders** - optional interceptor that allows adding new headers every time time the exporter is going to send spans.
+This is optional and can be used if headers are changing over time. This is a sync callback.
+
+## Viewing your traces
