 2. After making changes you can add them to git locally using `git add <file_name>`(to add changes only in a particular file) or `git add .` (to add all changes).
 3. After adding the changes you need to commit them using `git commit -m '<commit message>'`(look at the commit guidelines below for commit messages).
 4. Once you have successfully commited your changes, you need to push the changes to the forked repo on github using: `git push origin <branch_name>`.(Here branch name must be name of the branch you want to push the changes to.)
