**1. Create Extension in yii2.** As for this step, you can refer to [Create Extension](https://github.com/yiisoft/yii2/blob/master/docs/guide/structure-extensions.md "create extension") In short, you can use gii to create extension after read above article. Just be care to change the output as
```php
@app/vendor/yourname ``` change the namespace as
```php

yourname\yourwidgetname\
```You can link your github account now.
~~~   
 
```bash $ git config --global user.name "Your Name" $ git config --global user.email "email@example.com" ~~~```
 
And then add files. ~~~
 
```bash git add <file1> git add <file2> git status git commit -m "your comment" ~~~``` Remote github. ~~~  
 
```bash $ ssh-keygen -t rsa -C "youremail@example.com" ~~~```
 

You will find .ssh dir in you home dir, and find id_rsa和id_rsa.pub
You can tell id-rsa.pub to everyone.After that
~~~
 
```bash $ git remote add origin git@github.com:youraccount/yourrepository.git $ git push -u origin master i```
 
 
It will need input your github account and pass since use -u. In future, you only need below  
 
```bash
$ git push origin master ~~~```
