 #### Traits
 
-ctags doesn't indexes [traits](http://php.net/traits) by default, you have to add a `--regex-php` option to index them:
+[universal-ctags] supports traits natively (with `--php-kinds=cfit`).
+
+If you can't use universal-ctags, the `--regex-php` argument allows to extract traits:
 
-    ctags -R --PHP-kinds=+cf --regex-php=/^[ \t]*trait[ \t]+([a-z0_9_]+)/\1/t,traits/i
+    ctags -R --PHP-kinds=cfi --regex-php="/^[ \t]*trait[ \t]+([a-z0_9_]+)/\1/t,traits/i"
 
-Alternatively, create a `~/.ctags` file with the following contents:
+You can also create a `~/.ctags` file with the following contents:
 
     --regex-php=/^[ \t]*trait[ \t]+([a-z0_9_]+)/\1/t,traits/i
 
-You could also use [this patched version of ctags](https://github.com/shawncplus/phpcomplete.vim/wiki/Patched-ctags)
+Note that using `--regex-php=` is 10x slower than using universal-ctags.
