 These values are adjustable within the code and can be fine-tuned based on desired fluid dynamics.
 
-### Equations
-The SPH fluid simulation relies on specific equations for density, pressure, and force calculations, leveraging smoothing kernels:
-
-1. **Density Calculation**  
-   The Poly6 kernel is used to compute density based on particle distances:
-    $$ W_{\text{poly6}}(r) = \text{POLY6_CONST} \cdot (H^2 - r^2)^3 $$
-
-2. **Pressure Force**  
-   Pressure force between particles is calculated using the Spiky kernel gradient:
-   
-   $$ W'_{\text{spiky}}(r) = \text{SPIKY_GRAD_CONST} \cdot (H - r)^2 $$
-
-3. **Viscosity Force**  
-   The viscosity force is calculated with a Laplacian kernel:
-   
-   $$ \nabla^2 W_{\text{visc}}(r) = \text{VISC_LAP_CONST} \cdot (H - r) $$

+## Compile & Run

+
+### Dependencies
+
+* **CUDA Toolkit** – for CUDA language support, GPU parallelization, and CUDA/OpenGL interoperability
+* **GLEW** – for OpenGL Extension Wrangler Library
+* **freeGLUT** – for OpenGL windowing and event handling
+* **GLM** – for vector and matrix math operations in OpenGL
+* **Thrust** – for high-performance parallel algorithms (comes with the CUDA Toolkit)
+
+
+### Build Instructions
+
+1. **Install Dependencies**
+
+   On Ubuntu, you can install the required libraries using:
+   ```bash
+   sudo apt update
+   sudo apt install -y build-essential cmake libglew-dev freeglut3-dev libglm-dev
+   ```
+   Install the **CUDA Toolkit** from NVIDIA’s official site [here](https://developer.nvidia.com/cuda-toolkit), which includes both CUDA and Thrust libraries.
+    ```
+
+2. **Build the Project with CMake**
+
+   Navigate to the project src folder and create a `build` folder:
+   ```bash
+   mkdir build
+   cd build
+   ```
+
+   Run CMake to configure and generate the makefiles, then compile the code:
+   ```bash
+   cmake ..
+   make
+   ```
+
+   This will produce an executable named `cuda_opengl_integration` in the `build` directory.
+
+
+## Run
+
+   From the `build` directory, run the executable:
+   ```bash
+   ./cuda_opengl_integration
+   ```
