• Pluggable: Adds syntax extensions to extend the parser (see the plugin list).
• High speed (see our benchmarking tests)
• Easy to configure for security
• Member of Google's Assured Open Source Software

This is a Python port of markdown-it, and some of its associated plugins. For more details see: https://markdown-it-py.readthedocs.io.
