+## :desktop_computer: Graphical User Interface (GUI)
+
+A cross-platform graphical launcher is included in the module. It is powered by
+[AvaloniaUIShell](https://github.com/mdgrs-mei/AvaloniaUIShell) and requires
+**PowerShell 7.4 or newer**.
+
+### GUI Requirements
+
+| Requirement | Version |
+| ----------- | ------- |
+| PowerShell  | 7.4+    |
+| AvaloniaUIShell | latest |
+
+### Installing AvaloniaUIShell
+
+```powershell
+# Install the AvaloniaUIShell module
+Install-PSResource -Name AvaloniaUIShell
+
+# macOS / Linux only – add execute permission to the server binary:
+Enable-AUIExecution
+```
+
+### Launching the GUI
+
+```powershell
+# Option A – via the exported module function (recommended):
+Import-Module AsBuiltReport.System.Resources
+Start-AsBuiltReportGui
+
+# Option B – run the script directly:
+& "$((Get-Module AsBuiltReport.System.Resources).ModuleBase)\Src\GUI\Invoke-AsBuiltReportGui.ps1"
+```
+
+The GUI window lets you configure every common report parameter through a
+point-and-click interface:
+
+| Section | Controls |
+| ------- | -------- |
+| **Report Configuration** | Target, Output Folder (with folder browser), Report Name, Language |
+| **Output Formats** | HTML · Word · Text · Excel checkboxes |
+| **Options** | Timestamp · HealthCheck · Enable Diagrams · Export Diagrams · Diagram Theme |
+| **Info Level** | Per-section selectors (0 = Disabled, 1 = Summary, 2 = Detailed) for Date, TimeZone, Uptime, PSHost, ProcessInfo |
+| **Generate** | Progress bar · scrollable log showing live output |
+
+Report generation runs on a background thread so the window stays fully responsive.
+

+.SYNOPSIS
+    Graphical launcher for the System Resources As Built Report.
+.DESCRIPTION
+    Presents an Avalonia UI window (via the AvaloniaUIShell module) that lets the user
+    configure every common New-AsBuiltReport parameter through a point-and-click
+    interface and then generate the report without touching the command line.
+
+    Sections of the GUI:
+
+        Report Configuration  - Target, Output Folder, Report Name, Language
+        Output Formats        - Html / Word / Text / Excel checkboxes
+        Options               - Timestamp, HealthCheck, Diagrams, Export Diagrams,
+                                Diagram Theme
+        Info Level            - Per-section detail level (0 = Disabled, 1 = Summary,
+                                2 = Detailed) for Date, TimeZone, Uptime, PSHost,
+                                ProcessInfo
+        Generate              - Progress bar + scrollable log; report runs on a
+                                background thread so the UI stays responsive.
+
+.NOTES
+    Requirements:
+        - PowerShell 7.4 or newer  (AvaloniaUIShell requirement)
+        - AvaloniaUIShell module   (Install-PSResource -Name AvaloniaUIShell)
+        - AsBuiltReport.Core 1.6.2 or newer
+        - AsBuiltReport.System.Resources module (this module)
+
+    On macOS / Linux run Enable-AUIExecution once after installing AvaloniaUIShell.
+
+.EXAMPLE
+    # Launch the GUI from any PowerShell 7 prompt:
+    & "$PSScriptRoot\Invoke-AsBuiltReportGui.ps1"
+
+.EXAMPLE
+    # Or call the exported wrapper function after importing the module:

+    .SYNOPSIS
+        Launches the Avalonia UI graphical interface for generating a System Resources
+        As Built Report.
+    .DESCRIPTION
+        Opens an interactive window (powered by the AvaloniaUIShell module) that lets
+        the user configure and generate a System Resources As Built Report without
+        using the command line.
+
+        The GUI exposes the most common New-AsBuiltReport parameters:
+
+            - Target system name
+            - Output folder and report name
+            - Report language
+            - Output format (Html / Word / Text / Excel)
+            - Timestamp and HealthCheck toggles
+            - Diagram options (Enable, Export, Theme)
+            - Per-section InfoLevel (0-2) for Date, TimeZone, Uptime, PSHost,
+              and ProcessInfo
+
+        Report generation runs on a background thread, so the window stays fully
+        responsive while the report is being produced.
+
+    .NOTES
+        Requirements:
+            - PowerShell 7.4 or newer  (required by AvaloniaUIShell)
+            - AvaloniaUIShell module   (Install-PSResource -Name AvaloniaUIShell)
+            - AsBuiltReport.Core 1.6.2 or newer
+            - AsBuiltReport.System.Resources module (this module)
+
+        On macOS / Linux run Enable-AUIExecution once after installing AvaloniaUIShell.
+
+    .EXAMPLE
+        # Import the module then open the GUI:
+        Import-Module AsBuiltReport.System.Resources
+        Start-AsBuiltReportGui
