+## Basic usage
+
+### Folding
+
+Folding is enabled for headers by default.
+
+The following commands are useful to open and close folds:
+
+- `zr`: reduces fold level throughout the buffer
+- `zR`: opens all folds
+- `zm`: increases fold level throughout the buffer
+- `zM`: folds everything all the way
+- `za`: open a fold your cursor is on
+- `zA`: open a fold your cursor is on recursively
+- `zc`: close a fold your cursor is on
+- `zC`: close a fold your cursor is on recursively
+
+[Options](#options) are available to disable folding or change folding style.
+
+Try `:help fold-expr` and `:help fold-commands` for details.
+
+### Concealing
+
+Concealing is set for some syntax such as bold, italic, code block and link.
+
+Concealing lets you conceal text with other text. The actual source text is not modified. If you put your cursor on the concealed line, the conceal goes away.
+
+[Options](#options) are available to disable or change concealing.
+
+Try `:help concealcursor` and `:help conceallevel` for details.
+

 ### Set header folding level
 

-Folding level is a number between 1 and 6. By default, if not specified, it is set to 1.
+-   `g:vim_markdown_folding_level`

 
 

-```vim
-let g:vim_markdown_folding_level = 6
-```
+    Folding level is a number between 1 and 6. By default, if not specified, it is set to 1.

 
 

-Tip: it can be changed on the fly with:
+        let g:vim_markdown_folding_level = 6

 ### 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.
+-   `g:vim_markdown_toc_autofit`

 
 

-```vim

+
+### Text emphasis restriction to single-lines
+
+-   `g:vim_markdown_emphasis_multiline`
+
+    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 (i.e., for it to be applied a closing token must be found on the same line). To do so:
+
+        let g:vim_markdown_emphasis_multiline = 0

+    Concealing is set for some syntax.

 
 

-To enable/disable conceal use Vim's standard conceal configuration.
+    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.

 
 

-```vim
-set conceallevel = 2
-```
+    To enable conceal use Vim's standard conceal configuration.
+
+        set conceallevel=2
+
+    To disable conceal regardless of `conceallevel` setting, add the following to your `.vimrc`:
+
+        let g:vim_markdown_conceal = 0
+
+    To disable math conceal with LaTeX math syntax enabled, add the following to your `.vimrc`:
+
+        let g:tex_conceal = ""
+        let g:vim_markdown_math = 1
+
+-   `g:vim_markdown_conceal_code_blocks`
+
+    Disabling conceal for code fences requires an additional setting:
+
+        let g:vim_markdown_conceal_code_blocks = 0
+
+### Fenced code block languages
+
+-   `g:vim_markdown_fenced_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:
+
+        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']`.
+
+### Follow named anchors
+
+-   `g:vim_markdown_follow_anchor`
+
+    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`.
+
+-   `g:vim_markdown_anchorexpr`
+
+        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 `''`.

+
+    Strikethrough uses two tildes. `~~Scratch this.~~`
+

+
+### Adjust new list item indent
+
+-   `g:vim_markdown_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
+
+-   `g:vim_markdown_no_extensions_in_markdown`
+
+    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
+
+-   `g:vim_markdown_autowrite`
+
+    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
+
+-   `g:vim_markdown_auto_extension_ext`
+
+    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
+
+-   `g:vim_markdown_auto_insert_bullets`
+
+    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
+
+-   `g:vim_markdown_edit_url_in`
+
+    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'
