# This file is for setting up the Skywatch Automod service using Docker Compose.
#
# Before running `docker compose up`, you need to:
# 1. Create a `.env` file with your configuration. See the README.md for details.
# 2. (Optional but recommended) Create an empty `cursor.txt` file in this directory
#    to ensure Docker mounts a file, not a directory.
#    On Linux/macOS: touch cursor.txt
#
version: "3.8"
