+## About
+
+This project was developed as part of the course Geo-Visualization at the University of Groningen.
+It contains a CUDA-based raycaster which visualizes wind patterns using a silhouette shading.
+The program also includes various configuration options, which can be set as the program runs (see [Screenshots](#screenshots)).
+The program expects to use the MERRA2 dataset, which can be found [here](https://disc.gsfc.nasa.gov/datasets/M2I6NPANA_5.12.4/summary?keywords=M2I6NPANA_5.12.4).
+
+
+## Dependencies
+
+The project depends on a few libraries.
+Below is a list of these along with versions that _will_ work.
+Newer/older versions of the libraries may also compile and run properly, but this has not been tested.
+ * OpenGL[^1] Tested using the Mesa (1:24.3.3-2) driver.
+ * glfw3 (3.4-2)
+ * Cuda (12.6.3-1)
+ * Netcdf (4.9.2-6)
+ * Netcdf-cxx (4.3.1-4)
+ * Dear ImGUI (submodule within repository)
+
+
+## Installation
+
+Once all libraries are installed compiling the program is quite straightforward. First, initialize the Dear ImGUI submodule:
 ```bash
 git submodule update --init
 ```
 
-Then, compile using cmake:

+Make sure the program is executed on the nvidia GPU, or it will crash on startup.
+For example, on Arch the command `prime-run ./cuda-raytracer` would make sure the program utilizes the GPU.
