Now I'll be merging all your changes in to master branch of this project. Then your fork won't have those changes. In order to keep your fork synced with mine,
Add my repo's url as upstream remote url
git remote add upstream https://github.com/Roshanjossey/first-contributions
This is a way of telling git that another version of this project exists in the specified url and we're calling it master.
git fetch upstream
Here we're fetching all the changes in my fork (upstream remote)
git rebase upstream/master
Here you're applying all the changes you fetched to master branch. If you push master branch now, your fork will also have the changes
git push origin master
Notice here you're pushing to the remote named origin
