+## Introduction
+
+[Google Summer of Code](https://summerofcode.withgoogle.com) is a program that allows students to contribute to the development of open-source projects, mentored by participating organizations.
+
+Particle physics is an exciting field where large collaborations of scientists collect
+and analyze petabytes of data from high-energy physics experiments, such as those at the Large Hadron Collider,
+hosted at the CERN laboratory in Geneva, Switzerland.
+Some of the questions that we collectively ask are:
+
+- What are the fundamental blocks that make up our Universe?
+- What is the nature of dark matter and dark energy?
+- What is the nature of the asymmetry between matter and antimatter?
+- What was early Universe like?
+
+To answer these questions, particle physicists build software to simulate and analyze what happens in particle physics detectors.
+
+The CERN software for experiments (CERN EP-SFT) group has participated in the GSoC since 2011. Since 2017 the program has expanded to involve the high-energy physics community under the umbrella of the HEP Software Foundation.
+
+Information from last year’s GSoC can be found [here]({{ site.baseurl }}/gsoc/2024/index.html).
