- https://github.com/bubkoo/hexo-toc/ - 2 opened issues https://github.com/bubkoo/hexo-toc/issues/created_by/noraj
- https://github.com/shunitoh/hexo-toc-ext - use hexo-toc
- hexo helper https://hexo.io/docs/helpers.html#toc - but no plugin https://github.com/hexojs/hexo/issues/3287 and no min depth https://github.com/hexojs/hexo/issues/3288
- doctoc https://hsin919.github.io/2015/02/11/Add-TOC/, not the good way
- some renderer but bad behavior or incompatibility
- https://github.com/Oktavilla/markdown-it-table-of-contents - not a hexo plugin
this way
