This documentation aims to simplify and guide the way beginners make their first contribution. If you are looking to make your first contribution, follow the steps below.
If you're not comfortable with command line, here are tutorials using GUI tools.
If you don't have git on your machine, install it.
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 code button and then click the copy to clipboard icon.
Open a terminal and run the following git command:
git clone "url you just copied"
where "url you just copied" (without the quotation marks) is the url to this repository (your fork of this project). See the previous steps to obtain the url.
For example:
git clone https://github.com/this-is-you/DSA.git
where this-is-you is your GitHub username. Here you're copying the contents of the first-contributions repository on GitHub to your computer.
Change to the repository directory on your computer (if you are not already there):
cd DSA
Now create a branch using the git checkout command:
git checkout -b your-new-branch-name
For example:
git checkout -b add-new-file
(The name of the branch does not need to have the word add in it, but it's a reasonable thing to include because the purpose of this branch is to add your name to a list.)
Now open add or edit file in a text editor. Add code for any existing algorithm in other language or add some new algorithms. Make sure to update correspond README.md file if needed. Now, save the file.
If you go to the project directory and execute the command git status, you'll see there are changes.
Add those changes to the branch you just created using the git add command:
git add "name of the file you add or edit"
Now commit those changes using the git commit command:
git commit -m "Add message for the change"
Push your changes using the command git push:
git push origin <add-your-branch-name>
replacing <add-your-branch-name> with the name of the branch you created earlier.
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.
Soon after reviewing all your changes will be merged into the master branch of this project. You will get a notification email once the changes have been merged.
Congrats! You just completed the standard fork -> clone -> edit -> pull request workflow that you'll encounter often as a contributor!
