+## 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.

+### 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:
+
+```vim
+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`.
+
+```vim
+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 `''`.

+### Change default file extension

+```vim
+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:
+
+```vim
+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:
+
+```vim
+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:
+
+```vim
+let g:vim_markdown_edit_url_in = 'tab'
