在bitbucket 申請完免費帳號後， 如果當初申請帳號，是使用第三方登入googel等，需要到setting設定你的密碼  。

->setting ->connect accounts ->connect github


連結完成後，就可以使用github帳號登入。

在本地電腦。

1. git init

2. git remote add origin 網址

3. git pull origin master --allow-unrelated-histories

4. 編輯vim ，ESC跳出，在底下打w 存檔，最後用q離開編輯頁面回到指令\。

5. git commit -m "first"

6. git pull origin master

7. git push origin master  應該就可以成功。

備註會有錯誤產生原因可能是因為:
repo上面已經有一個 readme檔案，導致衝突
顯示以下訊息:! [rejected] master -> master (fetch first)

error: failed to push some refs to 'https://github.com/******/*****.git
hint: Updates were rejected because the remote contains work that you do
hint: not have locally. This is usually caused by another repository pushing
hint: to the same ref. You may want to first integrate the remote changes
hint: (e.g., 'git pull ...') before pushing again.
hint: See the 'Note about fast-forwards' in 'git push --help' for details.

但又遇到問題了，error message如下：
! [rejected] master -> master (non-fast-forward)
error: failed to push some refs to 'https://github.com/*****/*****.git'
hint: Updates were rejected because the tip of your current branch is behind
hint: its remote counterpart. Integrate the remote changes (e.g.
hint: 'git pull ...') before pushing again.
hint: See the 'Note about fast-forwards' in 'git push --help' for details.

輸入git pull origin master就解決了。
而會發生以上問題的原因，是因為有local branch 和 origin branch的問題。
