+# Dockerfile for FHIRFLARE-IG-Toolkit (Optimized for Python/Flask)
+#
+# This Dockerfile builds a container for the FHIRFLARE-IG-Toolkit application.
+#
+# Key Features:
+# - Uses python:3.11-slim as the base image for a minimal, secure Python runtime.
+# - Installs Node.js and global NPM packages (gofsh, fsh-sushi) for FHIR IG tooling.
+# - Sets up a Python virtual environment and installs all Python dependencies.
+# - Installs and configures Supervisor to manage the Flask app and related processes.
+# - Copies all necessary application code, templates, static files, and configuration.
+# - Exposes ports 5000 (Flask) and 8080 (optional, for compatibility).
+# - Entrypoint runs Supervisor for process management.
+#
+# Notes:
+# - The Dockerfile is optimized for Python. Tomcat/Java is not included.
+# - Node.js is only installed if needed for FHIR IG tooling.
+# - The image is suitable for development and production with minimal changes.
