+This repository provides an **agent-based simulation** of tumour-derived organoids and their interaction with **CAR T-cell therapy**.
+Developed as part of Google Summer of Code 2025, the project is released under the **Apache License 2.0**.
+
+The simulation integrates computational modeling and biological insights to explore tumour–immune dynamics and assess treatment outcomes under various scenarios.

+
+## Project Overview
+
+This project implements an **agent-based model** to simulate the behavior of *tumour-derived organoids* (lab-grown tumour models) and their response to **CAR T-cell therapy**.
+
+With this simulation, researchers can:
+- Recreate in vitro conditions for tumour growth.
+- Introduce CAR T-cells and analyze their effectiveness in solid tumor microenvironments.
+- Explore different treatment strategies and parameter variations.
+- Evaluate outcomes such as tumour reduction, elimination, or relapse risk.
+
+By adjusting biological and therapeutic parameters, the model enables **in silico experimentation** to complement laboratory research.
+
+---
+
+## Dependencies
+
+- [BioDynaMo](https://biodynamo.org/) (tested with version 1.05.132)
+- CMake ≥ 3.13
+- GCC or Clang with C++17 support
+- GoogleTest (for unit testing)
+
+**Note:** Ensure BioDynaMo is installed and sourced before running the simulation.
+
+---
+
+## Installation
+
+Clone the repository:
+```bash
+git clone https://github.com/compiler-research/CARTopiaX.git
+cd CARTopiaX
+
+```
+
+---
+
+## Building the Simulation
+
+**Option 1:**
+Use BioDynaMo’s build system:
+```bash
+biodynamo build
+```
+
+**Option 2:**
+Manual build:
+```bash
+mkdir build && cd build
+cmake ..
+make -j <number_of_processes>
+```
+
+---
+
+## Running the Simulation
+
+After building, run the simulation using one of the following methods:
+
+**Option 1:**
+With BioDynaMo:
+```bash
+biodynamo run
+```
+
+**Option 2:**
+Directly from the build directory:
+```bash
+
+./build/CARTopiaX
+```
+
+---
+
+## Results
+
+Data about tumor growth and diffrent types of cell populations is output in ./output/final_data.csv
+
+To visualize the results in paraview use:
+```bash
+paraview ./output/CARTopiaX/CARTopiaX.pvsm
+
+```
+
