 Integrate PHP CS Fixer (https://github.com/FriendsOfPHP/PHP-CS-Fixer).
 
 This plugin will execute the php-cs-fixer command
 on the directory or file (depends on which command you call).
 
 ==============================================================================
+MAPPINGS					    *vim-php-cs-fixer-mappings*
+
+<leader>pcd		Calls php-cs-fixer on the current directory of
+			the file.
+
+<leader>pcf		Calls php-cs-fixer on the current file.
+
+
+To change default mappings, there are two commands available to you.
+`PhpCsFixerFixDirectory()`
+`PhpCsFixerFixFile()`
+
+A possible remapping could be
+`nnoremap <silent><leader>d :call PhpCsFixerFixDirectory()<CR>`
+`nnoremap <silent><leader>f :call PhpCsFixerFixFile()<CR>`
