 ## Project Status
 
-[OpenTelemetry Signal Status for Rust][otel-signals-rust]. Libraries adhere to [Stability Guarantees.][otel-signal-stability]
+| Signal  | Status     |
+| ------- | ---------- |
+| Logs    | Alpha*     |
+| Metrics | Alpha      |
+| Traces  | Beta       |
+
+*OpenTelemetry Rust is not introducing a new end user callable Logging API.
+Instead, it provides [Logs Bridge
+API](https://github.com/open-telemetry/opentelemetry-specification/blob/main/specification/logs/bridge-api.md),
+that allows one to write log appenders that can bridge existing logging
+libraries to the OpenTelemetry log data model. The following log appenders are
+available:
+
+* [opentelemetry-appender-log](opentelemetry-appender-log/README.md)
+* opentelemetry-appender-tracing // TODO: Add link once available
+* opentelemetry-appender-slog // TODO: Add link once available
+
+If you already use the logging APIs from above, continue to use them, and use
+the appenders above to bridge the logs to OpenTelemetry. If you are using a
+library not listed here, feel free to contribute a new appender for the same.
+
+If you are starting fresh, then consider using
+[tracing](https://github.com/tokio-rs/tracing) as your logging API. It supports
+structured logging and is actively maintained.
+
+Project versioning information and stability guarantees can be found
+[here](VERSIONING.md).
