+zsh-syntax-highlighting / highlighters / line
+=================================================
+
+This is the ***line*** highlighter, that highlights the whole line.
+
+
+How to activate it
+------------------
+To activate it, add it to `ZSH_HIGHLIGHT_HIGHLIGHTERS`:
+
+    ZSH_HIGHLIGHT_HIGHLIGHTERS=( [...] line)
+
+
+How to tweak it
+---------------
+This highlighter defines the following styles:
+
+* `line` - the style for the whole line
+
+To override one of those styles, change its entry in `ZSH_HIGHLIGHT_STYLES`, for example in `~/.zshrc`:
+
+    ZSH_HIGHLIGHT_STYLES[line]='bold'
+
+The syntax for declaring styles is [documented here](http://zsh.sourceforge.net/Doc/Release/Zsh-Line-Editor.html#SEC135).
