-# OpenTelemetry Propagator gRPC Census
-
-[![NPM Published Version][npm-img]][npm-url]
-[![Apache License][license-image]][license-image]
-
-OpenTelemetry gRPC Census propagator provides gRPC header propagation for systems that use the OpenCensus 'grpc-trace-bin' binary header format. This allows for context propagation when either:
-
-- incoming gRPC calls come from services already instrumented using OpenCensus
-- outgoing gRPC calls go to services already instrumented using OpenCensus
-
-This propagator works in conjunction with the OpenTelemetry [gRPC plugin](https://github.com/open-telemetry/opentelemetry-js/tree/main/packages/exporter-trace-otlp-grpc).
-
-Example of usage:
-
-```javascript
-const { NodeTracerProvider } = require('@opentelemetry/sdk-trace-node');
-const { GrpcCensusPropagator } = require('@opentelemetry/propagator-grpc-census-binary');
-const { registerInstrumentations } = require('@opentelemetry/instrumentation');
-const { GrpcInstrumentation } = require('opentelemetry/instrumentation-grpc');
-
-const provider = new NodeTracerProvider();
-
-// Register GrpcCensusPropagator so we can propagate content using
-// the 'grpc-trace-bin' header in our incoming/outgoing gRPC calls.
-provider.register({
- propagator: new GrpcCensusPropagator()
-});
-
-registerInstrumentations({
- instrumentations: [
- new GrpcInstrumentation(),
- ],
-});
-
-```
-
-Also, see [examples/grpc-census-prop](../../examples/grpc-census-prop) for a
-worked example that shows when this propagator can be useful.
-
-## Implementation Details
-
-See [binary-format.ts](https://github.com/census-instrumentation/opencensus-node/blob/master/packages/opencensus-propagation-binaryformat/src/binary-format.ts) for equivalent encoding/decoding of the format in OpenCensus. Note: the author of the OpenCensus binary format, [@mayurkale22](https://github.com/mayurkale22), also created BinaryTraceContext.ts in [opentelemetry-core](https://github.com/open-telemetry/opentelemetry-js/tree/main/packages/opentelemetry-core) but that was subsequently removed as part of PR [#804](https://github.com/open-telemetry/opentelemetry-js/pull/804). The implementation of GrpcCensusPropagator in _this_ module uses a version of BinaryTraceContext.ts inspired by Mayur's previous work (with minor modifications e.g. there is no longer a BinaryFormat interface to implement).
