+Ultra  fast alternative to prometheus for open telemetry data in (development | testing | staging ) environments.
 
 Test , experiment and verify your open telemetry instrumentation before pushing things 
 to production.
 
+**Designed for rapid prototyping with grafana Explore**
 
 # Features
 
-- **Native grafana compatibility**: works with native prometheus. loki and tempo data sources.
+- **Native grafana compatibility**: works with native prometheus data sources.
 - **Single binary,zero dependency**
-- **Supports `PromQL` , `LogQL` and `TraceQL`**
+- **Supports `PromQL`**
 - **Standard Ingestion**: Support `otlp` and `otlphttp`. Send data via `gRPC`, `http/json` `http/protobuf`
 - **Painless**: Just point your otel collector, or send the data directly via otlp.
