+# Linux Patch Manager
+
+**Enterprise-class secure web-based management interface for controlling patching and updates on Linux servers and workstations.**
+
+## Overview
+
+Linux Patch Manager provides a centralized web interface to manage patching and software updates across a fleet of Linux servers and workstations. It communicates with managed devices through the [Linux Patch API](https://gitea.moon-dragon.us/echo/linux_patch_api), leveraging mTLS-secured RESTful endpoints for all operations.
+
+## Key Features
+
+- **Centralized Dashboard** — Monitor patch status across all managed hosts from a single interface
+- **Multi-Distribution Support** — Manage Debian/Ubuntu, RHEL/CentOS/Fedora, Alpine, and Arch hosts
+- **Secure by Design** — mTLS authentication, role-based access control, audit logging
+- **Batch Operations** — Apply patches and updates across multiple hosts simultaneously
+- **Scheduling** — Plan and schedule patch windows with approval workflows
+- **Reporting** — Compliance reporting and patch status dashboards
+
+## Architecture
+
+Linux Patch Manager is a web application that acts as a management plane, communicating with the Linux Patch API agent running on each managed host.
