This is the upstream version of Vim's included syntax highlighting rules and filetype settings for Mermaid.js.
Note
You generally don't need to install these files, as they are occasionally merged by Vim downstream.
From Vim 8.0 onward, users can follow the setup instructions in :help packages.
What about pathogen, vim-plug, plug.nvim, lazy.nvim, bundle, minipac, ... ?
Please refer to the documentation of that specific package manager.
