+# ImpTune
+
+## What This Is
+
+A self-hosted webapp (single Docker container) that lets IT technicians configure printer deployments and export ready-to-deploy packages for Microsoft Intune or NinjaRMM. It handles driver packaging, printer settings, install script generation, and .intunewin wrapping — all from a simple browser UI.
+
+## Core Value
+
+Generate a complete, working printer deployment package (script + drivers + icon) in minutes instead of manually scripting each printer setup.
+
+## Requirements
+
+### Validated
+
+(None yet — ship to validate)
+
+### Active
+
+- [ ] Upload or reference driver packages (ZIP/INF) from local storage or network share
+- [ ] Configure all printer parameters: name, IP/port, color/BW, duplex, paper size, default tray, and other common settings
+- [ ] Generate PowerShell install script that detects user vs. SYSTEM context and self-elevates when run by a user
+- [ ] Export full Intune package (.intunewin) with bundled drivers, script, and custom icon
+- [ ] Export NinjaRMM package (ZIP with PS script + driver files)
+- [ ] Organize printers by client/tenant in a single no-auth interface
+- [ ] Remember uploaded driver packages across sessions (minimal persistence)
+- [ ] Run as a single Docker container with minimal dependencies
+
+### Out of Scope
+
+- User authentication / separate logins — internal tool on private network
+- Full deployment history / audit log — not needed for v1
+- Direct Intune/Ninja API integration (push deployments) — export packages only
+- Mobile app — desktop browser only
+
+## Context
+
+- Target users: MSP technicians managing printers across multiple client sites
+- Multi-brand environment: HP, Canon, Ricoh, Brother, and others
+- IntuneWinAppUtil.exe will be bundled inside the container (or its format reimplemented) to produce .intunewin files
+- NinjaRMM deployments are script-based — a ZIP with PowerShell + drivers is the deliverable
+- The generated PowerShell script must handle elevation: detect if running as SYSTEM (Intune/RMM) or as a user, and self-elevate if needed
+- Intune deployments need a selectable app icon embedded in the package
+- No authentication required — the app runs on a private/internal network
+
+## Constraints
+
+- **Deployment**: Single Docker container — no external database, message queue, or sidecar services
+- **Dependencies**: Minimal — the fewer runtime dependencies the better
+- **Platform**: Generated scripts target Windows endpoints (PowerShell 5.1+)
+- **Persistence**: Lightweight — store driver packages on a Docker volume, use SQLite or flat files for config
+
+## Key Decisions
+
+| Decision | Rationale | Outcome |
+|----------|-----------|---------|
+| No authentication | Internal tool on private network, simplicity over security | — Pending |
+| Bundle IntuneWinAppUtil | Avoid requiring user to provide external tooling | — Pending |
+| Single Docker container | Minimal ops burden, easy to deploy and maintain | — Pending |
+| Minimal persistence (drivers only) | Printers configured fresh each time, reduces state management complexity | — Pending |
