+# LGTM Stack Deployment
+
+The **LGTM** stack is a comprehensive open-source observability platform powered by Grafana Labs. It provides unmatched correlation between metrics, logs, and traces, allowing complete visibility into your applications and infrastructure.
+
+## Components
+
+- **L**oki: Like Prometheus, but for logs. It is a horizontally-scalable, highly-available, multi-tenant log aggregation system.
+- **G**rafana: The open observability platform for visualization and analytics.
+- **T**empo: A high-volume, minimal dependency distributed tracing backend.
+- **M**imir: Scalable long-term storage for Prometheus metrics.
+
+## Deployment Guides
+
+This repository provides two guides to help you deploy the stack:
+
+### 1. Automated Deployment
+For a fully automated deployment using this stack, please follow the [Kubernetes Observability Guide](../docs/kubernetes-observability.md).
+
+### 2. Manual Deployment
+If you prefer to configure and deploy components manually, or need to understand the individual steps, please refer to the [Manual LGTM Deployment Guide](../docs/manual-lgtm-deployment.md).
