用VS2017上传项目到gitee，基本步骤如下：

第一步：在gitee上创建项目

第二步：初始化git仓库

E:\Develope\Material2017>git init

Reinitialized existing Git repository in E:/Develope/Material2017/.git/

第三步：添加远程仓库地址

E:\Develope\Material2017>git remote add origin https://gitee.com/clementine/Material.git

第四步：在执行pull

4.1提示文件merge

E:\Develope\Material2017>git pull origin master

remote: Counting objects: 3, done.

remote: Total 3 (delta 0), reused 0 (delta 0)

Unpacking objects: 100% (3/3), done.

From https://gitee.com/clementine/Material

* branch master -> FETCH_HEAD

* [new branch] master -> origin/master

error: The following untracked working tree files would be overwritten by merge:

README.md

Please move or remove them before you merge.

Aborting

按照提示删除md文件即可，再执行pull成功

E:\Develope\Material2017>git pull origin master

From https://gitee.com/clementine/Material

* branch master -> FETCH_HEAD

4.2提示拒绝合并

E:\Develope\SqlServerDataToolkit8.26\SqlServerDataToolkit>git pull origin master

From https://gitee.com/xxx

* branch master -> FETCH_HEAD

* [new branch] master -> origin/master

fatal: refusing to merge unrelated histories

遇到refusing to merge unrelated histories这个提示是因为两个仓库不同，发现refusing to merge unrelated histories，无法pull。要把两个不同的项目合并，git需要添加一句代码，在git pull，这句代码是在git 2.9.2版本发生的，最新的版本需要添加–allow-unrelated-histories

假如我们的源是origin，分支是master，那么我们 需要这样写

git pull origin master --allow-unrelated-histories

需要知道，我们的源可以是本地的路径

第五步：解决冲突

pull之后出现冲突，如果是首创项目，只有一个md文件，会报这个文件冲突，可以在VS2017里解决就，之后提交。

E:\Develope\SqlServerDataToolkit8.26\SqlServerDataToolkit>git pull origin master --allow-unrelated-histories

From https://gitee.com/clementine/SSDT

* branch master -> FETCH_HEAD

Auto-merging README.md

CONFLICT (add/add): Merge conflict in README.md

Automatic merge failed; fix conflicts and then commit the result.

第六步：提交、合并
