+OpenTelemetry Collector Exporter
+=============================
+
+|pypi|
+
+.. |pypi| image:: https://badge.fury.io/py/opentelemetry-ext-otcollector.svg
+   :target: https://pypi.org/project/opentelemetry-ext-otcollector/
+
+This library allows to export data to `OpenTelemetry Collector <https://github.com/open-telemetry/opentelemetry-collector/>`_.
+
+Installation
+------------
+
+::
+
+     pip install opentelemetry-ext-otcollector
+
+
+Usage
+-----
+
+The **OpenTelemetry Collector Exporter** allows to export `OpenTelemetry`_ traces to `OpenTelemetry Collector`_.
+
+.. code:: python
+
+    from opentelemetry import trace
+    from opentelemetry.ext.otcollector.trace_exporter  import CollectorSpanExporter
+    from opentelemetry.sdk.trace import TracerSource
+    from opentelemetry.sdk.trace.export import BatchExportSpanProcessor
+
+    trace.set_preferred_tracer_source_implementation(lambda T: TracerSource())
+    tracer = trace.get_tracer(__name__)
+
+    # create a CollectorSpanExporter
+    collector_exporter = CollectorSpanExporter(
+        # optional:
+        # endpoint="myCollectorUrl:55678",
+        # service_name="test_service",
+        # host_name="http://localhost",
+    )
+
+    # Create a BatchExportSpanProcessor and add the exporter to it
+    span_processor = BatchExportSpanProcessor(collector_exporter)
+
+    # add to the tracer
+    trace.tracer_source().add_span_processor(span_processor)
+
+    with tracer.start_as_current_span("foo"):
+        print("Hello world!")
