Why should you contribute to open-source projects?

You can contribute to all of the above-mentioned open-source projects - but why should you, exactly? Here are the most important reasons why it’s a good idea.

1. Improving the project

The greatest beauty of an open-source community is that its members are primarily driven by their genuine interest in the projects at hand. Therefore, a lot of people contribute to open-source projects because out of altruistic reasons - they want to improve it!

Making the open-source software run faster, smarter, or making it more secure will add to its quality. Since open-source software is transparent and free to use by anybody, your contribution can help people all over the world!

2. Building your confidence

Let’s imagine a scenario where you want to improve your coding skills in Java, C++, or Python. However, you don’t know how you actually stand nor where you need to improve - in other words, you have no mentor to guide you.

By contributing to open-source projects, you get immediate feedback on your work! You can also receive very specific instructions on how to improve parts of your code. This helps you to improve your work and build your confidence as a developer.

3. Gaining valuable knowledge

By emerging yourself into a certain open-source project, you’re getting valuable knowledge about the software at hand. In other words, you’re not just learning by doing - you’re learning by interacting with other developers’ code.

Moreover, you are getting insight into how an app works from the beginning to the end. Acquiring such knowledge isn’t comparable to anything theoretical you may learn.

4. Leveraging your career prospects

By contributing to open-source projects, you are signaling your talent to potential employers. For them, it’s easy to check your actual work and evaluate if you’d be a good fit for their open roles. In the words of Frank Scheffler, "active open source contributions emphasize your expertise and knowledge, more than certificates alone will ever do”.

Moreover, by contributing to multiple projects, you’re building your network of contacts, which can never hurt your career!

🔓 Here are some inspirational quotes on open-source from industry influencers. Hopefully, it will fuel you with motivation to explore and contribute to an open-source project!

How to contribute to an open-source project?

There are numerous open-source projects for beginners - but how do you get started?

Here’s a quick summary of Open Source Guide on How to Contribute to Open Source:

1. Where to find open-source projects to contribute to?

You might wonder where to even start when deciding to take a chance and contribute to an open-source project. You might want to explore these websites:

There, you will likely find cool open-source projects and detailed instructions on how to contribute to them.

2. How to spot a good project to contribute to?

There are a couple of ways to determine if the project you want to contribute to is worth your time. 

First of all, see if it has a license in the root of the repository to eliminate the chances of the project not being open source.

After that, check how active the project is. Are the latest commit and pull requests recent? Is there multiple contributors? Are the opened issues and pull requests responded to quickly? Are issues getting closed?

If you determine that the project is active, it’s probably a good one to contribute to!

3. How to actually contribute to an open source project?

First of all, look for contributing docs in the repository to determine what sort of contribution is accepted and what the process looks like. You won’t find this file in every project though.

Secondly, you don’t have to necessarily contribute code! You can help with design, help to improve the project’s documentation, organize duplicate issues, and more.

Of course, most of the open-source contributors contribute code. Here’s how you can do it:

  • Open an issue if you need to report an error, propose a new feature, or discuss a high-level topic. Communicate directly and give context to your proposal.
  • Open a pull request if you want to submit easy fixes (smaller error), or start working on a contribution that was already discussed in an open issue.
