+### Change fold style
+
+To fold in a style like [python-mode](https://github.com/klen/python-mode), add the following to your `.vimrc`:
+
+```vim
+let g:vim_markdown_folding_style_pythonic = 1
+```
+
+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.
+
+### 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
+```

+### 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
+```
+
+### Text emphasis restriction to single-lines
+
+By default text emphasis works across multiple lines until a closing token is found. However, it's possible to restrict text emphasis to a single line (ie, for it to be applied a closing token must be found on the same line). To do so:
+
+```vim
+let g:vim_markdown_emphasis_multiline = 0
+```
+
+### Syntax Concealing
+
+Concealing is set for some syntax.
+
+For example, conceal `[link text](link url)` as just `link text`.
+
+To enable conceal use Vim's standard conceal configuration.
+
+```vim
+set conceallevel=2
+```
+
+To disable conceal regardless of `conceallevel` setting, add the following to your `.vimrc`:
+
+```vim
+let g:vim_markdown_conceal = 0
+```
+
+### Fenced code block languages
+
+You can use filetype name as fenced code block languages for syntax highlighting.
+If you want to use different name from filetype, you can add it in your `.vimrc` like so:
+
+```vim
+let g:vim_markdown_fenced_languages = ['csharp=cs']
+```
+
+This will cause the following to be highlighted using the `cs` filetype syntax.
+
+    ```csharp
+    ...
+    ```
+
+Default is `['c++=cpp', 'viml=vim', 'bash=sh', 'ini=dosini']`.

+### Adjust new list item indent
+
+You can adjust a new list indent. For example, you insert a single line like below:
+
+```
+* item1
+```
+
+Then if you type `o` to insert new line in vim and type `* item2`, the result will be:
+
+```
+* item1
+    * item2

 ```
 
 ```
 

+vim-markdown automatically insert the indent. By default, the number of spaces of indent is 4. If you'd like to change the number as 2, just write:
+
+```vim
+let g:vim_markdown_new_list_item_indent = 2

 ## Mappings
 
 The following work on normal and visual modes:
 

-- `]]`: go to next header. `<Plug>(Markdown_MoveToNextHeader)`
-- `[[`: go to previous header. Contrast with `]c`. `<Plug>(Markdown_MoveToPreviousHeader)`
-- `][`: go to next sibling header if any. `<Plug>(Markdown_MoveToNextSiblingHeader)`
-- `[]`: go to previous sibling header if any. `<Plug>(Markdown_MoveToPreviousSiblingHeader)`
-- `]c`: go to Current header. `<Plug>(Markdown_MoveToCurHeader)`
-- `]u`: go to parent header (Up). `<Plug>(Markdown_MoveToParentHeader)`
+-   `gx`: open the link under the cursor in the same browser as the standard `gx` command. `<Plug>Markdown_OpenUrlUnderCursor`
+
+    The standard `gx` is extended by allowing you to put your cursor anywhere inside a link.
+
+    For example, all the following cursor positions will work:
+
+        [Example](http://example.com)
+        ^  ^    ^^   ^       ^
+        1  2    34   5       6
+
+        <http://example.com>
+        ^  ^               ^
+        1  2               3
+
+    Known limitation: does not work for links that span multiple lines.
+
+-   `]]`: go to next header. `<Plug>Markdown_MoveToNextHeader`
+
+-   `[[`: go to previous header. Contrast with `]c`. `<Plug>Markdown_MoveToPreviousHeader`

+-   `][`: go to next sibling header if any. `<Plug>Markdown_MoveToNextSiblingHeader`
+
+-   `[]`: go to previous sibling header if any. `<Plug>Markdown_MoveToPreviousSiblingHeader`
+
+-   `]c`: go to Current header. `<Plug>Markdown_MoveToCurHeader`
+
+-   `]u`: go to parent header (Up). `<Plug>Markdown_MoveToParentHeader`
+
+This plugin follows the recommended Vim plugin mapping interface, so to change the map `]u` to `asdf`, add to your `.vimrc`:
+
+    map asdf <Plug>Markdown_MoveToParentHeader
+
+To disable a map use:
+
+    map <Plug> <Plug>Markdown_MoveToParentHeader
