 # Redis Client Observability
 
-A helper repository for exploring Redis client observability with OpenTelemetry. This repo provides working examples in **Go (go-redis)** and **Python (redis-py)** along with a complete observability stack that you can spin up locally to easily try out Redis client metrics and tracing.
