+How to install
+--------------
+
+### Using packages
+
+* Arch Linux: [community/zsh-syntax-highlighting][arch-package] / [AUR/zsh-syntax-highlighting-git][AUR-package]
+* Gentoo: [mv overlay][gentoo-overlay]
+* Mac OS X / Homebrew: [brew install zsh-syntax-highlighting][brew-package]
+
+[arch-package]: https://www.archlinux.org/packages/zsh-syntax-highlighting
+[AUR-package]: https://aur.archlinux.org/packages/zsh-syntax-highlighting-git
+[gentoo-overlay]: http://gpo.zugaina.org/app-shells/zsh-syntax-highlighting
+[brew-package]: https://github.com/Homebrew/homebrew/blob/master/Library/Formula/zsh-syntax-highlighting.rb
+
+
+### In your ~/.zshrc
+
+Simply clone this repository and source the script:
+
+        git clone git://github.com/zsh-users/zsh-syntax-highlighting.git
+        echo "source ${(q-)PWD}/zsh-syntax-highlighting/zsh-syntax-highlighting.zsh" >> ~/.zshrc
+        source ~/.zshrc
+
+  If `git` is not installed, download and extract a snapshot of the latest
+  development tree from:
+
+        https://github.com/zsh-users/zsh-syntax-highlighting/archive/master.tar.gz
+
+  Note the `source` command must be **at the end** of `~/.zshrc`.
+
+
+### With oh-my-zsh
+
+Oh-my-zsh is a zsh configuration framework.  It lives at
+<http://github.com/robbyrussell/oh-my-zsh>.
+
+To install zsh-syntax-highlighting under oh-my-zsh:
+
+1. Clone this repository in oh-my-zsh's plugins directory:
+
+        git clone git://github.com/zsh-users/zsh-syntax-highlighting.git ~/.oh-my-zsh/custom/plugins/zsh-syntax-highlighting
+
+2. Activate the plugin in `~/.zshrc`:
+
+        plugins=( [plugins...] zsh-syntax-highlighting)
+
+3. Source `~/.zshrc`  to take changes into account:
+
+        source ~/.zshrc
+
+Note that `zsh-syntax-highlighting` must be the last plugin sourced,
+so make it the last element of the `$plugins` array.
+
+
+### System-wide installation
+
+Either of the above methods is suitable for a single-user installation,
+which requires no special privileges.  If, however, you desire to install
+zsh-syntax-highlighting system-wide, you may do so by running
+
+    make install
+
+and directing your users to add
+
+    source /usr/local/share/zsh-syntax-highlighting/zsh-syntax-highlighting.zsh
+
+to their `.zshrc`s.

+FAQ
+---
 
-* Download the script or clone this repository in [oh-my-zsh](http://github.com/robbyrussell/oh-my-zsh) plugins directory:
+### Why must `zsh-syntax-highlighting.zsh` be sourced at the end of the `.zshrc` file?
 
-        cd ~/.oh-my-zsh/custom/plugins
-        git clone git://github.com/zsh-users/zsh-syntax-highlighting.git
+`zsh-syntax-highlighting.zsh` wraps ZLE widgets.  It must be sourced after all
+custom widgets have been created (i.e., after all `zle -N` calls and after
+running `compinit`).  Widgets created later will work, but will not update the
+syntax highlighting.
 
-* Activate the plugin in `~/.zshrc` (in **last** position):

+zsh-syntax-highlighting / highlighters
+======================================
+
+Syntax highlighting is done by pluggable highlighters:
+
+* `main` - the base highlighter, and the only one [active by default][1].
+* `brackets` - [matches brackets][2] and parenthesis.
+* `pattern` - matches [user-defined patterns][3].
+* `cursor` - matches [the cursor position][4].
+* `root` - highlights the whole command line [if the current user is root][5].
+* `line` - applied to [the whole command line][6].
+
+[1]: highlighters/main.md
+[2]: highlighters/brackets.md
+[3]: highlighters/pattern.md
+[4]: highlighters/cursor.md
+[5]: highlighters/root.md
+[6]: highlighters/line.md
+
+
+How to activate highlighters
+----------------------------
+
+To activate an highlighter, add it to the `ZSH_HIGHLIGHT_HIGHLIGHTERS` array in
+`~/.zshrc`, for example:
+
+    ZSH_HIGHLIGHT_HIGHLIGHTERS=(main brackets pattern cursor)
+
+By default, `$ZSH_HIGHLIGHT_HIGHLIGHTERS` is unset and only the `main`
+highlighter is active.
+
+
+How to tweak highlighters
+-------------------------
+
+Highlighters look up styles from the `ZSH_HIGHLIGHT_STYLES` associative array.
+Navigate into the [individual highlighters' documentation](highlighters/) to
+see what styles (keys) each highlighter defines; the syntax for values is the
+same as the syntax of "types of highlighting" of the zsh builtin
+`$zle_highlight` array, which is documented in [the `zshzle(1)` manual
+page][zshzle-Character-Highlighting].
+
+[zshzle-Character-Highlighting]: http://zsh.sourceforge.net/Doc/Release/Zsh-Line-Editor.html#Character-Highlighting
+
+Some highlighters support additional configuration parameters; see each
+highlighter's documentation for details and examples.
+
+
+How to implement a new highlighter
+----------------------------------
+
+To create your own `myhighlighter` highlighter:
+
+* Create your script at
+    `highlighters/${myhighlighter}/${myhighlighter}-highlighter.zsh`.
+
+* Implement the `_zsh_highlight_myhighlighter_highlighter_predicate` function.
+  This function must return 0 when the highlighter needs to be called and
+  non-zero otherwise, for example:
+
+        _zsh_highlight_myhighlighter_highlighter_predicate() {
+          # Call this highlighter in SVN working copies
+          [[ -d .svn ]]
+        }
+
+* Implement the `_zsh_highlight_myhighlighter_highlighter` function.
+  This function does the actual syntax highlighting, by modifying
+  `region_highlight`, for example:
+
+        _zsh_highlight_myhighlighter_highlighter() {
+          # Colorize the whole buffer with blue background
+          region_highlight+=(0 $#BUFFER bg=blue)
+        }
+
+* Activate your highlighter in `~/.zshrc`:
+
+        ZSH_HIGHLIGHT_HIGHLIGHTERS+=(myhighlighter)

 zsh-syntax-highlighting / highlighters
 ======================================
 
-Syntax highlighting is done by pluggable highlighters:
+Navigate into the individual highlighters' documentation to see
+what styles (`$ZSH_HIGHLIGHT_STYLES` keys) each highlighter defines.
 
-* [***main***](highlighters/main) - the base highlighter, and the only one active by default.
-* [***brackets***](highlighters/brackets) - matches brackets and parenthesis.
-* [***pattern***](highlighters/pattern) - matches user-defined patterns.
-* [***cursor***](highlighters/cursor) - matches the cursor position.
-* [***root***](highlighters/root) - triggered if the current user is root.
-
-
-How to activate highlighters
-----------------------------
-
-To activate an highlighter, add it to the `ZSH_HIGHLIGHT_HIGHLIGHTERS` array in `~/.zshrc`, for example:
-
-    ZSH_HIGHLIGHT_HIGHLIGHTERS=(main brackets pattern cursor)
-
-
-How to tweak highlighters
--------------------------
-
-Highlighters look up styles from the `ZSH_HIGHLIGHT_STYLES` array. Navigate into each highlighter directory to see what styles it defines and how to configure it.
-
-
-How to implement a new highlighter
-----------------------------------
-
-To create your own ***myhighlighter*** highlighter:
-
-* Create your script at **highlighters/*myhighlighter*/*myhighlighter*-highlighter.zsh**.
-* Implement the `_zsh_highlight_myhighlighter_highlighter_predicate` function. This function must return 0 when the highlighter needs to be called, for example:
-
-        _zsh_highlight_myhighlighter_highlighter_predicate() {
-          # Call this highlighter in SVN repositories
-          [[ -d .svn ]]
-        }
-
-* Implement the `_zsh_highlight_myhighlighter_highlighter` function. This function does the actual syntax highlighting, by modifying `region_highlight`, for example:
-
-        _zsh_highlight_myhighlighter_highlighter() {
-          # Colorize the whole buffer with blue background
-          region_highlight+=(0 $#BUFFER bg=blue)
-        }
-
-* Activate your highlighter in `~/.zshrc`:
-
-        ZSH_HIGHLIGHT_HIGHLIGHTERS+=(myhighlighter)
+Refer to the [documentation on highlighters](../docs/highlighters.md) for further
+information.

+  # - :sudo_arg:   The argument to a sudo leading-dash option that takes one,
+  #                when given as a separate word; i.e., "foo" in "-u foo" (two
+  #                words) but not in "-ufoo" (one word).
+  # - :regular:    "Not a command word", and command delimiters are permitted.
+  #                Mainly used to detect premature termination of commands.
+  #
+  # When the kind of a word is not yet known, $this_word / $next_word may contain
+  # multiple states.  For example, after "sudo -i", the next word may be either
+  # another --flag or a command name, hence the state would include both :start:
+  # and :sudo_opt:.
+  #
+  # The tokens are always added with both leading and trailing colons to serve as
+  # word delimiters (an improvised array); [[ $x == *:foo:* ]] and x=${x//:foo:/} 
+  # will DTRT regardless of how many elements or repetitions $x has..

+  # the current state --- that is, the value of $this_word --- for two iterations
+  # (one for the redirection operator, one for the word following it representing
+  # the redirection target).  Therefore, we set $in_redirection to 2 upon seeing a
+  # redirection operator, decrement it each iteration, and stall the current state
+  # when it is non-zero.  Thus, upon reaching the next word (the one that follows
+  # the redirection operator and target), $this_word will still contain values
+  # appropriate for the word immediately following the word that preceded the
+  # redirection operator.
+  #
+  # The "the previous word was a redirection operator" state is not communicated
+  # to the next iteration via $next_word/$this_word as usual, but via

-------------------
-To activate it, add it to `ZSH_HIGHLIGHT_HIGHLIGHTERS`:
-
-    ZSH_HIGHLIGHT_HIGHLIGHTERS=( [...] pattern)
-
-
-How to tweak it
----------------
-To use this highlighter, associate patterns with styles in the `ZSH_HIGHLIGHT_PATTERNS` array, for example in `~/.zshrc`:
-
-    # To have commands starting with `rm -rf` in red:
-    ZSH_HIGHLIGHT_PATTERNS+=('rm -rf *' 'fg=white,bold,bg=red')
-
-The syntax for declaring styles is [documented here](http://zsh.sourceforge.net/Doc/Release/Zsh-Line-Editor.html#SEC135).
