+
+## Project Status
+
+| Signal  | Status                 | Project                                                                  |
+| ------- | ---------------------- | ------------------------------------------------------------------------ |
+| Traces  | Public Release         | N/A                                                                      |
+| Metrics | Alpha        [1]       | N/A                                                                      |
+| Logs    | Experimental [2]       | N/A                                                                      |
+
+* [1]: The metric collection pipeline is available for testing purpose. Not
+      ready for production. The earlier implementation (based on old
+      specification) can be included in build by setting
+      `ENABLE_METRICS_PREVIEW` preprocessor macro, and is included under
+      `*/_metrics/*` directory. This would be eventually removed once the
+      ongoing implemetation is stable.
+* [2]: The current Log Signal Implementation is Experimental, and will change as
+      the current OpenTelemetry Log specification matures. The current
+      implementation can be included in build by setting `ENABLE_LOGS_PREVIEW`
+      preprocessor macro.
+
+## OpenTelemetry Specification Compatibility Matrix
+
+| API Version | Core Version | Contrib Version         |
+| ----------- |--------------|-------------------------|
+| 1.0.0       | 1.0.0-rc4    | N/A [1]                 |
+| 1.0.0       | 1.0.0        | N/A                     |
+
+* [1]: We don't have releases for opentelemetry-cpp contrib repo. This may
+      change in future.
+
+## Supported C++ Versions
+
+Code shipped from this repository generally supports the following versions of
+C++ standards:
+
+* ISO/IEC 14882:2011 (C++11, C++0x)
+* ISO/IEC 14882:2014 (C++14, C++1y)
+* ISO/IEC 14882:2017 (C++17, C++1z)
+* ISO/IEC 14882:2020 (C++20)
+
+Any exceptions to this are noted in the individual `README.md` files.
+
+Please note that supporting the [C Programming
+Language](https://en.wikipedia.org/wiki/C_(programming_language)) is not a goal
+of the current project.
+
+## Supported Development Platforms
+
+ Our CI pipeline builds and tests on following `x86-64` platforms:
+
+| Platform                                                            |   Build type  |
+|---------------------------------------------------------------------|---------------|
+| ubuntu-20.04 (Default GCC Compiler - 9.3.0)                         | CMake, Bazel  |
+| ubuntu-18.04 (GCC 4.8 with -std=c++11 flag)                         | CMake [1]     |
+| ubuntu-20.04 (Default GCC Compiler - 9.3.0 with -std=c++20 flags)   | CMake, Bazel  |
+| macOS 10.15 (Xcode 12.2)                                            | Bazel         |
+| Windows Server 2019 (Visual Studio Enterprise 2019)                 | CMake, Bazel  |
+
+[1]: Bazel build is disabled for GCC 4.8, as gRPC library 1.38 and above
+  (required by OTLP expoter) don't build with this compiler. See gRPC [official
+  support](https://grpc.io/docs/#official-support) document. CMake build doesn't
+  build OTLP exporter with GCC 4.8.
+
+In general, the code shipped from this repository should build on all platforms
+having C++ compiler with [supported C++ standards](#supported-c-versions).
+
+## Dependencies
+
+Please refer to [Dependencies.md](docs/dependencies.md) for OSS Dependencies and
+license requirements.
+
+## Installation
+
+Please refer to [INSTALL.md](./INSTALL.md).
+
+## Getting Started
+
+As an application owner or the library author, you can find the getting started
+guide and reference documentation on
+[opentelemetry-cpp.readthedocs.io](https://opentelemetry-cpp.readthedocs.io/en/latest/)
+
+The `examples/simple` directory contains a minimal program demonstrating how to
+instrument a small library using a simple `processor` and console `exporter`,
+along with build files for CMake and Bazel.
