+Fenced code block languages ~
+
+You can use filetype name as fenced code block languages for syntax

+in your '.vimrc' like so:
+>
+  let g:vim_markdown_fenced_languages = ['csharp=cs']

+Follow named anchors ~
+
+This feature allows the 'ge' command to follow named anchors in links of the
+form 'file#anchor' or just '#anchor', where file may omit the '.md' extension
+as usual. Two variables control its operation:
+>
+  let g:vim_markdown_follow_anchor = 1
+<
+This tells vim-markdown whether to attempt to follow a named anchor in a link
+or not. When it is 1, and only if a link can be split in two parts by the
+pattern '#', then the first part is interpreted as the file and the second one
+as the named anchor. This also includes urls of the form '#anchor', for which
+the first part is considered empty, meaning that the target file is the current
+one. After the file is opened, the anchor will be searched.
+
+Default is '0'.
+>
+  let g:vim_markdown_anchorexpr = "'<<'.v:anchor.'>>'"
+<
+This expression will be evaluated substituting 'v:anchor' with a quoted string
+that contains the anchor to visit. The result of the evaluation will become the
+real anchor to search in the target file. This is useful in order to convert
+anchors of the form, say, 'my-section-title' to searches of the form 'My
+Section Title' or '<<my-section-title>>'.
+
+Default is "''".

+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:
+>
+  let g:vim_markdown_new_list_item_indent = 2

+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:
+>
+  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:
+>
+  let g:vim_markdown_autowrite = 1

+Change default file extension ~
+
+If you would like to use a file extension other than '.md' you may do so using
+the 'vim_markdown_auto_extension_ext' variable:
+>
+  let g:vim_markdown_auto_extension_ext = 'txt'
+<

+Do not automatically insert bulletpoints ~
+
+Automatically inserting bulletpoints can lead to problems when wrapping text
+(see issue #232 for details), so it can be disabled:
+>
+  let g:vim_markdown_auto_insert_bullets = 0
+<
+In that case, you probably also want to set the new list item indent to 0 as
+well, or you will have to remove an indent each time you add a new list item:
+>
+  let g:vim_markdown_new_list_item_indent = 0

+Change how to open new files ~
+
+By default when following a link the target file will be opened in your current
+buffer. This behavior can change if you prefer using splits or tabs by using
+the 'vim_markdown_edit_url_in' variable. Possible values are 'tab', 'vsplit',
+'hsplit', 'current' opening in a new tab, vertical split, horizontal split, and
+current buffer respectively. Defaults to current buffer if not set:
+>
+  let g:vim_markdown_edit_url_in = 'tab'
