File needs to have extension .md or .markdown

[dariober]

This tripped me more than once when working on a new file without a name yet: If a file does not have a valid markdown extension (.md or .markdown, I think), vim does not see the vim-markdown-toc commands at all. Perhaps add a note on the README?

Thx for suggestion, I had add a note on the readme.
