+## New Instrumentation
+
+**Do not submit pull requests for new instrumentation without reading the following.**
+
+This project is dedicated to promoting the development of quality instrumentation using OpenTelemetry.
+To achieve this goal, we recognize that the instrumentation needs to be written using the best practices of OpenTelemetry, but also by developers that understand the package they are instrumenting.
+Additionally, the produced instrumentation needs to be maintained and evolved.
+
+The size of the OpenTelemetry JavaScript developer community is not large enough to support an ever-growing amount of instrumentation.
+Therefore, to reach our goal, we have the following recommendations for where instrumentation packages should live.
+
+1. Native to the instrumented package
+2. A dedicated public repository
+3. Here in the opentelemetry-js-contrib repository
+
+If possible, OpenTelemetry instrumentation should be included in the instrumented package.
+This will ensure the instrumentation reaches all package users, and is continuously maintained by developers that understand the package.
+
+If instrumentation cannot be directly included in the package it is instrumenting, it should be hosted in a dedicated public repository owned by its maintainer(s).
+This will appropriately assign maintenance responsibilities for the instrumentation and ensure these maintainers have the needed privilege to maintain the code.
+
+The last place instrumentation should be hosted is here in this repository.
+Maintaining instrumentation here hampers the development of OpenTelemetry for JavaScript and therefore should be avoided.
+When instrumentation cannot be included in a target package and there is good reason to not host it in a separate and dedicated repository an [instrumentation request](https://github.com/open-telemetry/opentelemetry-js-contrib/issues/new/choose) should be filed.
+Note that new instrumentation needs at least two contributors assigned to it as code-owners.  It is the responsibility
+of the requesting party to reach out and find code-owners for the proposed instrumentation. The instrumentation request
+needs to be accepted before any pull requests for the instrumentation can be considered for merging.
+
+Regardless of where instrumentation is hosted, it needs to be discoverable.
+The [OpenTelemetry registry](https://opentelemetry.io/registry/) exists to ensure that instrumentation is discoverable.
+You can find out how to add instrumentation to the registry [here](https://github.com/open-telemetry/opentelemetry.io#adding-a-project-to-the-opentelemetry-registry).
+
 ## Contributing Vendor Components
 
 This repo is generally meant for hosting components that work with popular open-source frameworks and tools. However, it is also possible to contribute components specific to a 3rd party vendor in this repo.

 **Instrumentations**: OpenTelemetry can collect tracing data automatically using instrumentations. Vendors/Users can also create and use their own.
+Please read the [contributing guidelines on adding new instrumentation](CONTRIBUTING.md#new-instrumentation) before opening any PRs.
 
 **Resource Detectors**: OpenTelemetry can collect resource attributes of the entity that producing telemetry. For example, a process producing telemetry that is running in a container on Kubernetes has a Pod name, it is in a namespace and possibly is part of a Deployment which also has a name. All three of these attributes can be included in the `Resource`.

-# 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).
