-### 环境配置
+# 4.0
 
-1、 安装cnpm加速
+This is a future version of mBlock. Based on Electron.
 
-> npm install -g cnpm --registry=https://registry.npm.taobao.org
+# Build guide
 
-（electron加速：修改node_modules\electron-download\build\index.js->baseUrl->https://npm.taobao.org/mirrors/electron/ ，或者export ELECTRON_MIRROR=https://npm.taobao.org/mirrors/electron/ ）
+Just standard npm stuff. You know that.
 
-2、 安装electron环境和serialport
-> ```cnpm install -g node-gyp```
+(If you want to use the Arduino features, put the arduino executable folder under /tools)
 
-On Unix:
-> python (v2.7 recommended, v3.x.x is not supported)
-> make
-> A proper C/C++ compiler toolchain, like GCC
+> npm install
+> npm run rebuild-serialport
+> npm run rebuild-hid
+> npm run rebuild-bluetooth
+> npm start
 
-On Mac OS X:
-> python (v2.7 recommended, v3.x.x is not supported) (already installed on Mac OS X)
-> Xcode
+# Translations
 
-On Windows( [Windows Vista / 7 only] requires .NET Framework 4.5.1):
-> ```cnpm install -g --production windows-build-tools``` 此处安装比较耗时，也可能因为网络原因安装失败，必须确保此步安装成功
-> ```cnpm install --save-dev electron-rebuild serialport node-hid bluetooth-serial-port electron-prebuilt```(为确保不受网络影响，可以使用代理服务器，如果有shadowsocks，可以设置```cnpm config set proxy=http://127.0.0.1:1080```)
-
-3、 编辑package.json， **新增scripts**
-
-> "scripts": {
->   "rebuild-serialport" :"electron-rebuild -f -w serialport",
->   "rebuild-hid" :"electron-rebuild -f -w node-hid",
->   "rebuild-bluetooth" :"electron-rebuild -f -w bluetooth-serial-port",
->   "start":"electron ."
-> }
-
-4、 为electron重新编译serialport,node-hid,bluetooth-serial-port(只需要编译一次)
-
-> ```cnpm run rebuild-serialport```
-> ```cnpm run rebuild-hid```
-> ```cnpm run rebuild-bluetooth```
-
-On Linux
-> ```sudo apt-get install libbluetooth-dev```
-> ```npm install```
-> ```./node_modules/.bin/electron-rebuild```
-
-5、 运行
-
-> ```cnpm start```

-### Arduino
-
-在云盘192.168.2.20/常用软件/mblock_tools里面，
-- Linux: 把arduino.tar.gz解压成为/tools/arduino
-- Mac: 把Arduino.app.zip解压成为/tools/Arduino.app
-- Windows: 
-
-### 编写代码注意事项
-
-获取文件绝对路径时，需用__root_path来拼接，不能直接用node的文件路径，如下：
-需要在web/tmp目录下写入文件project.sb2，假如运行脚本在app目录下，
-正确：var filename = "./tmp/project.sb2";
-var filePath = path.resolve(__root_path, './web', filename);
-fs.writeFileSync(filePath, data);
-错误：
-var filename = "./tmp/project.sb2";
-var filePath = path.resolve(__dirname, '../web', filename);
-fs.writeFileSync(filePath, data);
