+# Stockroom Inventory
+
+A Dockerized inventory system for computers, audio equipment, graphics hardware, long-play records, CDs, displays, peripherals, and other assets.
+
+## Run with Docker
+
+```bash
+docker compose up --build
+```
+
+Open http://localhost:5000. The SQLite database is stored in the persistent `inventory_data` Docker volume.
+
+## Features
+
+- Search by name, brand, model, serial number, asset tag, or location
+- Filter by item type and status
+- Add, edit, and delete inventory records
+- Computer fields: CPU, RAM, GPU, and disk/storage
+- Media field: format
+- CSV export of the currently visible inventory
+- Responsive web UI for desktop and mobile
+
+## Local development
+
+```bash
+python -m venv .venv
+.venv\\Scripts\\activate
+pip install -r requirements.txt
+python app.py
+```
