+# 🧠 Update Manager Architecture
+
+This document describes how Update Manager is structured internally and how data flows through the system.
+
+---
+
+## Overview
+
+Update Manager is a lightweight, SSH-based system for managing updates across multiple Linux hosts.
+
+It consists of two main layers:
+
+* **UI layer** – interactive menu (`update-manager-ui.sh`)
+* **Core engine** – update logic (`update-manager.sh`)
+
+The system is designed to be simple, transparent, and dependency-light.
+
+---
+
+## High-Level Flow
+
+```text
+User
+ ↓
+UI (update-manager-ui.sh)
+ ↓
+Core (update-manager.sh)
+ ↓
+SSH → Remote Hosts
+ ↓
+Results
+ ↓
+Logging (/opt/update-manager/log)
+ ↓
+UI / User
+```
+
+---
+
+## Components
+
+### UI Layer (`update-manager-ui.sh`)
+
+Responsible for:
+
+* Displaying menu (via `dialog`)
+* Handling user input
+* Managing hosts (add/remove/edit)
+* Providing access to logs
+* Delegating actions to core engine
+
+The UI does **not perform updates directly**.
+
+---
+
+### Core Engine (`update-manager.sh`)
+
+Responsible for:
+
+* Reading configuration
+* Parsing hosts file
+* Executing SSH commands
+* Checking for updates (`apt list --upgradable`)
+* Handling connection errors
+* Writing structured logs
+
+This is the **execution layer** of the system.
+
+---
+
+### Hosts Configuration
+
+File:
+
+```bash
+/opt/update-manager/hosts.conf
+```
+
+Format:
+
+```text
+name ip user
+```
+
+Example:
+
+```text
+server1 192.168.1.10 user
+server2 192.168.1.20 user
+server3 192.168.1.30 user
+```
+
+Each line represents a target system accessed via SSH.
+
+---
+
+### Logging System
+
+Log file:
+
+```bash
+/opt/update-manager/log/update-manager.log
+```
+
+Log format:
+
+```text
+YYYY-MM-DD HH:MM:SS [LEVEL] host - message
+```
+
+Example:
+
+```text
+2026-03-18 20:45:01 [INFO] lanx-www - Checking updates
+2026-03-18 20:45:03 [OK] lanx-www - 3 updates available
+2026-03-18 20:45:05 [ERR] lanx-db - Connection failed
+```
+
+#### Log Levels
+
+* `INFO` – informational messages
+* `OK` – successful operations
+* `ERR` – errors or failures
+
+Logging is centralized and written locally.
+
+---
+
+## Execution Flow
+
+For each host:
+
+1. Read host entry from `hosts.conf`
+2. Establish SSH connection
+3. Execute:
+
+```bash
+apt list --upgradable
+```
+
+4. Parse output
+5. Determine:
+
+ * Up-to-date
+ * Updates available
+ * Connection failure
+6. Write result to:
+
+ * terminal output
+ * log file
+
+---
+
+## Configuration
+
+Primary config:
+
+```bash
+/etc/update-manager.conf
+```
+
+Fallback:
+
+```bash
+./update-manager.conf
+```
+
+Supported options:
+
+* `HOSTS_FILE`
+* `SSH_OPTIONS`
+
+---
+
+## Design Principles
+
+* **No agents** – uses standard SSH only
+* **Simple over complex** – minimal dependencies
+* **Transparent behavior** – everything is visible/logged
+* **CLI-first** – designed for terminal environments
+* **Modular growth** – prepared for future extensions
+
+---
+
+## Future Architecture Direction
+
+Planned extensions:
+
+* Plugin system (modular features)
+* Web interface (optional UI layer)
+* Notification system (alerts)
+* Metrics / monitoring
+* Integration with Lanx AI
+
+---
+
+## Summary
+
+Update Manager follows a clean separation:
+
+* UI = interaction
+* Core = execution
+* Config = data
+* Log = output
+
+This keeps the system predictable, debuggable, and easy to extend.
