+Card import tool for [Final Fantasy TCG Complete](https://steamcommunity.com/sharedfiles/filedetails/?id=889160751) mod for the [Tabletop Simulator](http://berserk-games.com/tabletop-simulator/)
+
+
+## Quick Start
+
+If needed, customize `main.py` variables:
+
+- `opusid`: The Card opus you want to import
+- `num_threads`: Lower this for really weak systems
+- `opus_size`: 500 here means the script will correctly import anything containing *up to* 500 cards
+
+### using your system's `python3`
+
+1. Make sure `PIL` and `requests` python3 libraries (or equivalent) are installed.
+1. Run `main.py` in project root directory.
+
+### using a `docker` container
+
+1. Build the container using `docker build -t ldericher/fftcgtool .` in project root directory.
+1. Run `docker run --rm -it -v "$(pwd)/out:/app/out" ldericher/fftcgtool` in project root directory.
+
+
+## Future work
+
+- Add command line interface for `main.py` variables
+- Multiple opus import
