Inquiry About Customizing Mermaid Open Source Version

[crazywolf181]

Hi Mermaid team,
I’m exploring the use of Mermaid in a personal UI app and would like to understand what’s possible with the open-source version. Specifically, can I customize diagram behavior—like adding/editing nodes interactively—and extend Mermaid’s functionality in my own app? Would appreciate any guidance or documentation you could point me to.

Thanks
