-### Electron v4
-**!!! IMPORTANT !!!**\
-You **CANNOT** use `electron-rebuild`, it will download the prebuild-binary for electron v3, which is NOT compatible.There are 2 thing you need to do:
-1. download v4 [prebuild-binary](https://github.com/xVanTuring/cquant/releases/download/v0.0.18/cquant-v0.0.18-electron-v4-win32-x64.zip),unzip and copy to cquant' build folder.Look like:
-```
-cquant
-  --- \build
-    --- \Release
-      --- cquant.node
-```
-> Notice: you may find you version-specifc v4 prebuild-binary in [release](https://github.com/xVanTuring/cquant/releases),look like this `cquant-v0.0.x-electron-v4-win32-x64.zip`. x for version
-2. create a `cache file` for electron-prebuild, otherwise it will re-download the v3 version,if you use it for other native module.The final structure will be
-```
-cquant
-  --- \build
-    --- \Release
-      --- cquant.node
-      --- .forge-meta
-```
-and the .forge-meta contains
-``` 
-x64--64
-```
 
-### Electron v3
-1. install `electron-rebuild`
-2. run `.\node_modules\.bin\electron-rebuild`
 ## Build Your Self
 ### CMake
 You need to install [CMake](https://cmake.org/download/) based on your System.

 > for more info you can view project [cmake-js](https://github.com/cmake-js/cmake-js#installation)
 Basically you need run this command 
 ``` bash
-cmake-js -r electron -v 4.0.0 rebuild # for electron
+cmake-js -r electron -v 4.0.4 rebuild # for electron
 cmake-js -r node -v 10.0.0 rebuild # for node
 ```
 And of course if you use `electron-prebuild` make sure you add the `cache file` mentioned before
