First up, most probably you will want to contribute to the already existing repository. And I'm assuming you might have done all the id creation and git installation steps.
Basically you wil be using these set of commands:
• Go to the repository and copy it's link from "Add Code" section.
• Go to the folder where you want to create the local copy and open git bash by right clicking.
• Write command -> git clone <url you copied>
• Now you'll be having your repo in your folder get inside the same.
• Now you can either create a branch to separately add your code or you can commit your code their itself.
• Most probably you'll be creating branch.
• For creating branch get inside the repository which got cloned and then open git bash.
• Write command -> git checkout -b "Branch Name"
• Now you write your changes and commit it their in your branch
• For commiting the changes you must make sure that you are on the branch where you want the changes to be committed by you.
° If not on branch, type -> git checkout <branch name>
• Now at first send your changes to the staging area so as to be committed by typing -> git add .
• Now commit using -> git commit -m "Some message"
• Now before pushing your changes make sure you are having the latest pull from the base/master branch. For doing the same go to branch base/master by typing -> git checkout <master>
• Get all latest changes -> git pull
• Now again switch back to your branch by typing git checkout <your branch >
• Now merge your code with the master branch so as to take the latest changes on your branch by typing -> git merge master
• If there exists any merge conflict rectify it by opening your editor and making the necessary changes and then again add and commit it by following the above commiting steps.
• Finally push the changes you did by typing ->
git push origin <branch where you want to merge>
• That's it done.
• Hope you liked it :)
