+# MTG Python Deckbuilder ${VERSION}
+
+## Highlights
+- Direct-to-builder launch with automatic initial setup and tagging
+- Improved Type Summary (accurate Commander/Creature/etc. counts)
+- Smarter export filenames: full commander name + ordered themes + date, with auto-increment
+- TXT export duplication fixed
+- Post-build prompt to build another deck or quit
+
+## Docker
+- Multi-arch image (amd64, arm64) on Docker Hub
+- Persistent volumes:
+  - /app/deck_files
+  - /app/logs
+  - /app/csv_files
+
+### Quick Start
+```bash
+mkdir mtg-decks && cd mtg-decks
+
+docker run -it --rm \
+  -v "$(pwd)/deck_files":/app/deck_files \
+  -v "$(pwd)/logs":/app/logs \
+  -v "$(pwd)/csv_files":/app/csv_files \
+  mwisnowski/mtg-python-deckbuilder:latest
+```
+
+Windows PowerShell users: see WINDOWS_DOCKER_GUIDE.md or run:
+Invoke-WebRequest -Uri "https://raw.githubusercontent.com/mwisnowski/mtg_python_deckbuilder/main/run-from-dockerhub.bat" -OutFile "run-from-dockerhub.bat" run-from-dockerhub.bat
+
+## Changes
+- Auto-setup/tagging when `csv_files/cards.csv` is missing (both main and builder)
+- Main entrypoint now skips menu and launches the deck builder
+- Type summary classification matches export categories; uses snapshot fallback
+- Export filenames:
+  - Full commander name (punctuation removed)
+  - All themes in order
+  - Date suffix (YYYYMMDD)
+  - Auto-increment when file exists
+- Removed duplicate TXT sidecar creation in CSV export
+
+## Known Issues
+- First run downloads card data; may take several minutes
+- Ensure volume mounts are present to persist files outside the container
