+deoplete
+========
+
+Deoplete is the abbreviation of "dark powered neo-completion".  It
+provides asynchronous keyword completion system in the
+current buffer.  Deoplete cannot be customized and has not many
+features currently.  It is provided for testing purpose.
+
+**Note:** It is still alpha version!  It is not for production use.
+
+## Installation
+
+**Note:** deoplete requires Neovim(latest is recommended) with Python3 enabled.
+See [requirements](#requirements) if you aren't sure whether you have this.
+
+1. Extract the files and put them in your Neovim directory
+   (usually `~/.nvim/`).
+2. Execute the `:UpdateRemotePlugins` and restart Neovim.
+3. Execute the `:DeopleteEnable` command or set `let g:deoplete#enable_at_startup = 1`
+   in your `.nvimrc`
+
+## Requirements
+
+deoplete requires Neovim with if\_python3.
+If `:echo has("python3")` returns `1`, then you're done; otherwise, see below.
+
+You can enable Python3 interface with pip:
+
+    sudo pip3 install neovim
+
+If you want to read for Neovim-python/python3 interface install documentation,
+you should read `:help nvim-python`.
+
+## Screenshots
+
+Nothing...
+
+## Configuration Examples
+
+```vim
+" Use deoplete.
+let g:deoplete#enable_at_startup = 1
+```
