+1. Intro                                                    *simple-todo-into*
+
+Plugin provides handy mappings to manage simple todo lists.
+
+Supported format of todo list is similar to task lists used in GitHub Flavored
+Markdown. Read GitHub blog article for example:
+
+https://github.com/blog/1375-task-lists-in-gfm-issues-pulls-comments

+2. Mappings                                                 *simple-todo-maps*
+
+Plugin exposes some <Plug> maps. These maps are available for normal and
+insert modes.
+
+To completely disable default key bindings (which is pretty handy) use:
+>
+let g:simple_todo_map_keys = 0
+<
+                                                     *<Plug>(simple-todo-new)*
+<Plug>(simple-todo-new)
+<leader>i                   Create a new item
+
+                                                   *<Plug>(simple-todo-below)*
+<Plug>(simple-todo-below)
+<leader>o                   Create a new item below
+
+                                                   *<Plug>(simple-todo-above)*
+<Plug>(simple-todo-above)
+<leader>O                   Create a new item above
+
+                                            *<Plug>(simple-todo-mark-as-done)*
+<Plug>(simple-todo-mark-as-done)
+<leader>x                   Mark item under cursor as done.
+
+                                          *<Plug>(simple-todo-mark-as-undone)*
