# Using open-source code and libraries

Yes, in most cases, you can use open-source code or libraries in your hackathon project. Open-source code and libraries are often used by developers to save time and effort by reusing existing code that has been made available by others.

However, it's important to note that there may be rules and guidelines regarding the use of open-source code and libraries in a hackathon. Some hackathons may require participants to provide attribution to the original creators of the code or libraries used, while others may prohibit the use of certain libraries or code that may give some participants an unfair advantage.

Before using open-source code or libraries in your hackathon project, it's important to review the rules and guidelines of the hackathon to ensure that you are in compliance. If you have any questions about the use of open-source code or libraries in the hackathon, you can always contact the organizers for clarification.
