+the following to your `.vimrc`:
+
+```vim
+let g:vim_markdown_folding_style_pythonic = 1

+### 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

 ### Disable Default Key Mappings

 ```vim

 ## 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
