+
+The OpenTelemetry PHP team is pleased to announce that the
+[opentelemetry-php](https://github.com/open-telemetry/opentelemetry-php) library
+has progressed to Release Candidate stability. This release is the culmination
+of years of work from the OpenTelemetry PHP team. Thank you to all of the
+contributors, testers, and integrators that made this release happen. We most
+certainly couldn’t have made this release without the help of the community at
+large.
+
+This is the first release candidate we are publishing to garner further input
+from the community. This release offers support for tracing, metrics, and logs
+for PHP applications, as well as auto-instrumentation via a
+[PECL extension](https://pecl.php.net/package/opentelemetry). We will continue
+to refine the library as we receive bug reports, as well as moving towards a
+general availability release.
+
+## What happens next?
+
+We would love to see people testing the code against production-like workloads.
+Once we have confidence at scale with positive feedback from the community, we
+will move to general availability with a 1.0.0 release.
+
+We are also looking to promote our
+[contrib packages](https://github.com/open-telemetry/opentelemetry-php-contrib/)
+to RC and then GA, based on feedback from the community.
+
+## How can you help?
+
+If you are new to OpenTelemetry PHP, the best place to start is with the
+[getting started documentation](/docs/instrumentation/php/getting-started/).
+
+We are looking for developers to test this instrumentation in their PHP
+codebases. We are happy to triage any issues that might come up — please feel
+free to open an issue in our repository’s
+[GitHub issues](https://github.com/open-telemetry/opentelemetry-php/issues).
+Pull requests are also always welcome in any of our repositories:
