+let g:vim_markdown_folding_style_pythonic = 1
+```
+
+### Set header folding level
+
+Folding level is a number between 1 and 6. By default, if not specified, it is set to 1.
+
+```vim
+let g:vim_markdown_folding_level = 6
+```
+
+Tip: it can be changed on the fly with:
+
+```vim
+:let g:vim_markdown_folding_level = 1
+:edit
+```
+
+### Disable Default Key Mappings
+
+Add the following line to your `.vimrc` to disable default key mappings:
+
+```vim
+let g:vim_markdown_no_default_key_mappings = 1
+```
+
+You can also map them by yourself with `<Plug>` mappings.
+
+### Enable TOC window auto-fit
+
+Allow for the TOC window to auto-fit when it's possible for it to shrink.
+It never increases its default size (half screen), it only shrinks.
+
+```vim
+let g:vim_markdown_toc_autofit = 1
+```
+
+### Syntax Concealing
+
+Concealing is set for some syntax.
+
+For example, conceal `[link text](link url)` as just `link text`.
+
+To enable/disable conceal use Vim's standard conceal configuration.
+
+```vim
+set conceallevel=2
+```
