 == Introduction
 https://opentelemetry.io/docs/what-is-opentelemetry/[OpenTelemetry] is an Observability framework and toolkit designed to create and manage telemetry data such as traces, metrics, and logs. Crucially, OpenTelemetry is vendor- and tool-agnostic.
 
-Quarkus provides manual and automatic instrumentation for tracing and manual instrumentation  capabilities for metrics.
+Quarkus provides manual and automatic instrumentation for tracing and manual instrumentation capabilities for metrics.
 
 This will allow Quarkus based applications to be observable by tools and services supporting OpenTelemetry.
