+This section provides tutorials to familiarize you
+with some basic Keptn features
+and point you to other documentation that has more comprehensive information.
+
+Before attempting these tutorials, we recommend that you read the
+[Core Concepts]((../core-concepts/index.md)) section.
+
+## Keptn Metrics
+
+The Keptn Metrics component simplifies observability in Kubernetes
+by unifying and standardizing metrics from multiple data sources,
+such as Prometheus, Dynatrace, Datadog, and cloud providers like AWS, Google,
+and Azure.
+It integrates seamlessly with deployment and scaling tools like Argo,
+Flux, KEDA, and HPA, enabling automated decisions with minimal configuration.
+Unlike the Kubernetes Metrics Server, Keptn Metrics eliminates the complexity
+of maintaining multiple point-to-point integrations, offering a streamlined,
+centralized approach for managing metrics across diverse tools and observability platforms.
+
+## Keptn Observability
+
+Keptn enhances your cloud-native deployment environment with powerful observability
+features, whether or not you follow a GitOps strategy.
+This guide walks you through installing Keptn on a Kubernetes cluster, enabling
+Keptn for a namespace and deployment, and setting up Grafana and observability tools to
+visualize DORA metrics and OpenTelemetry traces.
+By the end, you’ll have a fully integrated observability system built step-by-step.
+
+## Release Lifecycle Management
+
+Keptn's Release Lifecycle Management tools enhance your cloud-native deployments by
+running pre- and post-deployment tasks, conducting SLO evaluations, and managing
+workload promotions.
+This tutorial introduces these tools and demonstrates how to configure Keptn to trigger
+webhooks around deployments.
+It builds on the **Getting Started with Keptn Observability** exercise, so completing
+that first is recommended.
+You'll learn to annotate workloads, group them into KeptnApp resources, and set
+up webhook triggers for robust deployment workflows.
