-EasyScheduler提交代码流程
-=====
+* First from the remote repository *https://github.com/analysys/EasyScheduler.git* fork code to your own repository
+
+* there are three branches in the remote repository currently:
+     * master normal delivery branch
+            After the stable version is released, the code for the stable version branch is merged into the master branch.
+
+    * dev daily development branch
+            The daily development branch, the newly submitted code can pull requests to this branch.
+
+    * branch-1.0.0 release version branch
+            Release version branch, there will be 2.0 ... and other version branches, the version 
+            branch only changes the error, does not add new features.
+
+* Clone your own warehouse to your local
+
+    `git clone https://github.com/analysys/EasyScheduler.git`
+
+* Add remote repository address, named upstream
+
+   `git remote add upstream https://github.com/analysys/EasyScheduler.git`
+
+* View repository:
+
+    `git remote -v`
+
+> There will be two repositories at this time: origin (your own warehouse) and upstream (remote repository)
+
+* Get/update remote repository code (already the latest code, skip it)
+
+   `git fetch upstream`
+
+
+* Synchronize remote repository code to local repository
+
+```
+git checkout origin/dev
+git merge --no-ff upstream/dev
+```
+
+If remote branch has a new branch `DEV-1.0`, you need to synchronize this branch to the local repository.
+
+```
+git checkout -b dev-1.0 upstream/dev-1.0
+git push --set-upstream origin dev1.0
+```
+
+* After modifying the code locally, submit it to your own repository:
+
+`git commit -m 'test commit'`
+`git push`
+
+* Submit changes to the remote repository
+
+* On the github page, click on the new pull request.
