  Level 1 heading which is served as a document title is not folded.
  `g:vim_markdown_folding_level` setting is not active with this fold style.
  
 +To prevent foldtext from being set add the following to your `.vimrc`:
 +
 +```vim
 +let g:vim_markdown_override_foldtext = 0
 +```

  ### Set header folding level
  
  Folding level is a number between 1 and 6. By default, if not specified, it is set to 1.

  Concealing is set for some syntax.
  
  For example, conceal `[link text](link url)` as just `link text`.
 +Also, `_italic_` and `*italic*` will conceal to just _italic_.
 +Similarly `__bold__`, `**bold**`, `___italic bold___`, and `***italic bold***`
 +will conceal to just __bold__, **bold**, ___italic bold___, and ***italic bold*** respectively.
  
  To enable conceal use Vim's standard conceal configuration.

+ ### Do not require .md extensions for Markdown links
+ 
+ If you want to have a link like this `[link text](link-url)` and follow it for editing in vim using the "ge" command, but have it open the file "link-url.md" instead of the file "link-url", then use this option:
+ 
+ ```vim
+ let g:vim_markdown_no_extensions_in_markdown = 1
+ ```
+ This is super useful for GitLab and GitHub wiki repositories.
+ 
+ Normal behaviour would be that vim-markup required you to do this `[link text](link-url.md)`, but this is not how the Gitlab and GitHub wiki repositories work. So this option adds some consistency between the two. 
+ 
+ ### Auto-write when following link
+ 
+ If you follow a link like this `[link text](link-url)` using the "ge" shortcut, this option will automatically save any edits you made before moving you:
+ 
+ ```vim
+ let g:vim_markdown_autowrite = 1
+ ```
