1. Fork the repository you want to contribute to using the fork button on GitHub.
2. Go to your forked repository on github and clone it to your local machine using the following command,

   git clone <parent_repo_link> 

   For this example, let's say the repository's name is test.
3. Go to powershell and access the cloned repository with,

   cd test/
   
   // Open with VSCode
   code . 

4. Create a new local branch named dev on your cloned repository using,

   git checkout -b dev

   Tip: To view all branches of the repository (local and remote) use,

   git branch -a

   To just view the remote branches use,

   git branch -r

5. Connect the local branch to an upstream using the following command,

   // We link our local branch to the parent repository by adding the parent repository as upstream
   git remote add upstream <link_to_parent_repository> 

6. Create necessary changes in the files, add and commit them using the normal git workflow with,

   git add .
   git commit -m "<your_commit_message>"
   

7. Push all the commits you've made on the dev branch using,

   git push origin dev

   This command not only pushes the changes to your branch, it also publishes your local branch to your remote forked repository. Now it should show up as a different branch in the branches dropdown on GitHub.

Once your happy with the changes on your branch, you can push all the changes in your repository to the parent repository with a pull request. You need to go to the parent repository and create a pull request on the pull requests tab. The owner of the parent repository will then be able to merge your code to one of their branches and comment on the changes that you've made.

To pull changes from the parent repository, change into the branch you want to pull changes into using,

git checkout dev

Then,

git fetch upstream
git merge upstream/main

Note: Here, upstream/main refers to the main branch of the upstream repository, i.e., the parent repository.

If you need to update a different branch, you need to checkout into that branch and run the commands to fetch and merge changes.

To delete a branch, make sure you checkout into a branch that isn't the one you need to delete. Then, you need to first delete the local and the remote instances with,

git branch --delete dev
git push origin --delete dev
