-## Overview
+Maidroid を作り出すには, まず空の卵と卵に命を吹き込むための, Maidroid-Egg Writer を作成しなければなりません.
+それらのレシピを以下に示します.
 
-- MaidroidはCoreと呼ばれるチップを埋め込まれると、そのチップに埋め込まれたプログラムを実行する
-- CoreはCoreWriterと呼ばれるチップへの書き込みを行う機械を使うことで、様々なチップへ変換することができる
+<img src="http://i.imgur.com/6ZGQF4J.png" />
+<img src="http://i.imgur.com/Y5tzPGM.png" />
 
-## Core
+次に, Maidroid-Egg Writer 設置, 右クリックし, `Egg` と書かれたスロットに先ほど作成した空の卵を置きます.
+また, `Fuel` と書かれたスロットには石炭を, `Dye` と書かれたスロットには染料を設置します.
+この染料の色によって, 生成される卵の種類が変化します.
+以下に染料と, 生成される卵の対応を示します.
 
-Coreの種類とその機能の説明を以下に示す。

-|`maidroid_core:basic`|プレーヤーの後ろを付いてくる。荷物持ちくらいにはなる|
+|`dye:red`|`maidroid:maidroid_mk1_egg`|
 
-## Crafting
+しばらく待つと, 空の卵に命が吹き込まれ, 新しい卵に変換されます.
+この卵を取り出し地面に投げつけると, Maidroid が誕生します.

+この状態では, Maidroid は止まったままです.
+Maidroid を動かすためには, Core, つまり Maidroid の脳を埋め込む必要があります.
+Core を作り出す手順は Maidroid を作り出す手順と非常に似ています.

 # Maidroid
-Maidroid is a mod for Minetest which adds maid robots that can perform common tasks such as farming and cutting down trees.
 
-![A screenshot of maid robots from the Maidroid mod](screenshot_readme.png)
+## Overview
+
+Maidroid MOD is a MOD for Minetest which adds maid robots, inspired by littleMaidMob.
+
+## Usage
+
+First, in order to create a maidroid, you have to craft an empty egg and an egg writer that convert eggs.
+Those recipe is as follows.
+
+<img src="http://i.imgur.com/6ZGQF4J.png" />
+<img src="http://i.imgur.com/Y5tzPGM.png" />
+
+After you place an egg writer node, and rightclick it, you have to place an empty egg to the slot labeled `Egg`, a coal to the slot labeled `Fuel`, and a dye to the slot labeled `Dye`.
+The kind of the dye placed decides a egg produced.
+The correspondences are as follows.
+
+|Dye|Egg|
+|:--|:--|
+|`dye:red`|`maidroid:maidroid_mk1_egg`|
+
+After a while, the empty egg will be converted to an new egg.
+If you take and use it, a new maidroid will be born.
+
+The maidroid, however, doesn't move now.
+In order to have them move, you have to put a Core that is their brain.
+You can create a core in a similar way to a maidroid egg.
+First, you have to create an empty core and a core writer.
+Those recipe is as follows.
+
+<img src="http://i.imgur.com/Sxnr38Y.png">
+<img src="http://i.imgur.com/97VENIl.png">
+
+After you place a core writer node, rightclick it, and place a empty core to the slot labeled `Core`, a coal to the slot labeled `Fuel`, and a dye to the slot labeled `Dye`.
+The correspondences of dyes and cores are as follows.
+
+|Dye|Core|Description|
+|:--|:--|:--|
+|`dye:red`|`maidroid_core:basic`|Following the player.|
+
+When a new core is created, put it to the maidroid.
+Rightclick it, and put the core to the slot labeled `Core`.
+The maidroid will start.
