# What is Open Source? [**Open source**](https://opensource.com/resources/what-open-source) software is software with *source code* that anyone can inspect, modify, and enhance. *"Source code"* is the part of software that most computer users don't ever see; it's the code computer programmers can manipulate to change how a piece of software—a "program" or "application"—works. Programmers who have access to a computer program's source code can improve that program by adding features to it or fixing parts that don't always work correctly. In order to allow agencies and organizations that can leverage the CHIME app to make time sensitive decisions, Penn is open sourcing the code so it can be used and customized to these agencies' needs. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
