Let's make a contribution to this repository.

Let me show you how easy it is:

Fork this repository by clicking on the fork button on the top of this page. This will create a copy of this repository in your account.

Now clone the forked repository to your machine. Go to your GitHub account, open the forked repository, click on the clone button and then click the copy to clipboard icon.
Now let's bring the cloned repository to your local machine.
git clone <url-you-just-copied>
For example:
git clone https://github.com/harshareddy794/HACTOBERFEST2020.git

Since you want to change the files inside, first let's move to the folder correctly. Use the following command on terminal:
cd HacktoberFest2020

Since now you're about to make your personal changes to the project, it's always a better idea to make a new branch. Run the following command:

git checkout -b <branch_name>
For example:
git checkout -b new_branch

Check out the CONTRIBUTE.md file to see what all contributions can you make.

It's finally that time when you commit your changes and leave a beautiful commit message behind. You can run the following commands:

git add .
git commit -m "<Message>"
For example:
git commit -m "Added a script"

Finally, push your changes to Github:
To do so run the following command:

git push origin <your-branch-name>
For example:
git push origin branch_name

If you go to your repository on GitHub, you'll see a Compare & pull request button. Click on that button. Now submit the pull request. Leave a custom message if you want.
