Submit Code

First from the remote repository https://github.com/apache/seatunnel.git fork a copy of the code into your own repository
There are currently three branches in the remote repository:
- dev daily development branch
  Every day dev development branch, newly submitted code can pull request to this branch.
- 3.2.0-release release version branch
  The release version branch, there will be 4.0...and other version branches in the future.

Clone your repository to your local

git clone https://github.com/apache/seatunnel

Add remote repository address, named upstream

git remote add upstream https://github.com/apache/seatunnel

View repository
```
git remote -v
```
At this time, there will be two repositories: origin (your own repository) and upstream (remote repository)
Get/Update remote repository code
```
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 such as dev-1.0, you need to synchronize this branch to the local repository
```
git checkout -b dev upstream/dev-1.0
git push --set-upstream origin dev-1.0
```
After modifying the code locally, submit it to your own repository:
```
git commit -m 'commit content'
git push
```
Submit changes to the remote repository
On the github page, click "New pull request".
Select the modified local branch and the branch you want to merge with the past, click "Create pull request".
Then the community Committers will do CodeReview, and then he will discuss some details (including design, implementation, performance, etc.) with you. When everyone on the team is satisfied with this modification, the commit will be merged into the dev branch
Finally, congratulations, you have become an official contributor to Apache SeaTunnel !
