* Download the latest version of OMO CEP from [**mods.one**](https://mods.one/mod/cep).
* [**Open your OMORI game folder**](/install/installing-omo-cep.md#open-game-folder) in Dolphin Explorer.

## Add New Files

* In another Dolphin Explorer window, unzip your OMO CEP Lite download and locate the **www** folder inside.
* Drag and drop the **www** folder into your **OMORI** game folder.

Make sure you are dropping into the main **OMORI** game folder, not the **www** subfolder!
