+* You must have the
+[auto-complete](https://github.com/auto-complete/auto-complete) package. Also,
+[yasnippet](https://github.com/capitaomorte/yasnippet) and
+[popwin](https://github.com/m2ym/popwin-el) are recommended.

+  please set the variable `dcd-exectutable` and `dcd-server-executable`
+  using `M-x customize`.
 
 ## Setup
-* First, follow the Setup section in the root README.
-* Second, add the following to your .emacs. With this setting, dcd-server starts automatically when you open file in d-mode.  (Of course, you should edit ```path_to_ac-dcd.el``` to suit your enviroment.)

-* Third, set import path using ```M-x customize-variable RET ac-dcd-flags```.
-* When something is wrong, please check variables with ```M-x customize-apropos RET ac-dcd``` and restart server with ```M-x ac-dcd-init-server```.
+* You can set import paths using `M-x customize-variable RET ac-dcd-flags`.
+* Alternatively, if you're using [DUB](http://code.dlang.org/) to manage your
+  project, you can use `M-x ac-dcd-add-imports` to add import paths of the
+  current project automatically.
+* When something is wrong, please, check variables with `M-x customize-apropos
+  RET ac-dcd` and restart server with `M-x ac-dcd-init-server`.
 
 ## Features
+
 * Dlang source for auto-complete
 * Function calltip expansion with yasnippet
-* Show ddoc with ```C-c ?```
-* Goto definition with ```C-c .```
-* After goto definition, you can pop to previous position with ```C-c ,```
+* Show ddoc with `C-c ?`
+* Goto definition with `C-c .`
+* After goto definition, you can pop to previous position with `C-c ,`
 
 ## TODO
-* Multi byte character support (Need help!)
+
+* UTF-8 support is in place. However, UTF-16 and UTF-32 may not work correctly.
