The round indicators next to snippet icons hint at the snippet’s relative complexity level (green - beginner, yellow - intermediate, red - advanced). They help us classify snippets by taking into account things such as number of concepts, code length and abstraction level. These indicators should be taken with a grain of salt, as learning paths may vary from one individual to the next.

OSCC stands for Open Source Community Contribution and is used in place of individual authors for snippets with multiple contributors. It's our little way of saying thanks to all the people who have put in time and effort to make our content better.

Any content issues should be reported using the GitHub Issue Tracker for each individual content repository. Use the GitHub link on the snippet page to find the appropriate repository and then open an issue describing the problem.

There are no specific requirements for contributing to 30 seconds of code, except for reading and understanding our contribution guidelines. These can be found on each individual repository, while some more general guidelines can be found here.

Note, however, that contributions to 30 seconds of code might be locked temporarily due to scheduled maintenance or heavy load of content curation. We do this to ensure that all contributions are processed in time and that no significant disruptions occur.

You can go to the 30 seconds of code organization on GitHub and find the appropriate repository. After reading the contribution guidelines, you can use the relevant template to create your snippet and submit a Pull Request for us to review.
