+# POPS — Printing Operations Production System
+
+A web-based production management system for 3D print farms.
+
+## Features
+
+- **Printer overview** — see all printers and their current status at a glance
+- **Job queue** — track what is printing now and what is in the pipeline
+- **Status updates & to-do lists** — stay on top of ongoing work
+- **Filament database** — connect to and manage your filament inventory
+- **Price calculator** — calculate job costs
+- **Print log** — keep a history of completed print jobs
+
+## Stack
+
+- **Backend:** FastAPI
+- **Frontend:** Web UI (served by FastAPI)
+- **Database:** MySQL (managed via Alembic migrations)
+- **Deployment:** Docker
+
+## Getting Started
