 # Better Rainbow Parentheses
 
+Forked from https://github.com/kien/rainbow_parentheses.vim since that now
+appears to be unmaintained.
+
 ### Options:
 
+The colours used; the outermost pair is coloured with the last colour in the
+list, the next-outermost with the second-last colour, etc. The first element of
+each entry is the terminal colour, the second element is the GUI (gvim) colour.
 ```vim
 let g:rbpt_colorpairs = [
+    \ ['red',         'RoyalBlue3'],
+    \ ['brown',       'SeaGreen3'],
+    \ ['blue',        'DarkOrchid3'],
+    \ ['gray',        'firebrick3'],
+    \ ['green',       'RoyalBlue3'],
+    \ ['magenta',     'SeaGreen3'],
+    \ ['cyan',        'DarkOrchid3'],
+    \ ['darkred',     'firebrick3'],
     \ ['brown',       'RoyalBlue3'],
-    \ ['Darkblue',    'SeaGreen3'],
-    \ ['darkgray',    'DarkOrchid3'],
-    \ ['darkgreen',   'firebrick3'],
-    \ ['darkcyan',    'RoyalBlue3'],
-    \ ['darkred',     'SeaGreen3'],
-    \ ['darkmagenta', 'DarkOrchid3'],
-    \ ['brown',       'firebrick3'],
-    \ ['gray',        'RoyalBlue3'],
-    \ ['black',       'SeaGreen3'],
-    \ ['darkmagenta', 'DarkOrchid3'],
-    \ ['Darkblue',    'firebrick3'],
+    \ ['darkblue',    'DarkOrchid3'],
+    \ ['gray',        'firebrick3'],
     \ ['darkgreen',   'RoyalBlue3'],
-    \ ['darkcyan',    'SeaGreen3'],
-    \ ['darkred',     'DarkOrchid3'],
+    \ ['darkmagenta', 'SeaGreen3'],
+    \ ['darkcyan',    'DarkOrchid3'],
     \ ['red',         'firebrick3'],
     \ ]
 ```
 
+How deep to colour (repeating the colour list if necessary) before giving up;
+limited for performance reasons.
 ```vim
-let g:rbpt_max = 16
+let g:rbpt_max = 15
 ```
 
 ```vim
 let g:rbpt_loadcmd_toggle = 0
 ```
 
+Also bold parenthese to make the colours stand out more.
+```vim
+let g:bold_parentheses = 1      " Default on
+```
+
 ### Commands:
 
 ```vim
