+# Benchmarking setup
+
+In this folder, I run some benchmarks on everyone's code.
+
+## How to benchmark
+
+1. Make sure you have the appropriate software installed. You can do so by
+activating the Nix shell as defined in `shell.nix`, or you can view everyone's
+installation requirements in the
+[software requirements](#Software-requirements) section.
+
+2. Run benchmarks by executing the respective scripts. For example, if you
+wish to benchmark Bram's code, you may run `bram.sh` in your terminal. All data
+will be collected in the `data/` folder.
+
+3. Once you have collected all the data you wanted to collect, you can open the
+Jupyter Notebook by typing `jupyter notebook Benchmarks.ipynb` in the terminal.
+
+4. In the Jupyter Notebook, evaluate all cells and gain the graphs you want.
+Graphs are also stored in the `img/` folder.
+
+## Software requirements
+
+To create the measurements, this benchmarking setup uses
+[hyperfine](https://github.com/sharkdp/hyperfine). To build the visualization,
+this setup uses [Jupyter Notebooks](https://jupyter.org/) - but you can install
+the dependencies listed in `requirements.txt` to get all necessary packages
+installed.
+
+Bob uses [Python](https://www.python.org/).
+
+Bram uses [Rust](https://rust-lang.org/) at version 1.86.0.
+
+Brechtje uses [Python](https://www.python.org/).
+
+Sander uses [GHCup](https://www.haskell.org/ghcup/) at version 9.6.7. Haskell
+typically opens as a REPL from which functions can be evaluated, so some
+liberties are taken here. The script is reformatted in the `sander_hs/` folder
+and compiled to a binary in order to approximate performance.

+-- AOC 2025 - Sander
+
+-- so for those wondering about how I run this Haskell code, here's the setup:
+-- 1) install GHCup as instructed from https://www.haskell.org/ghcup/
+-- 2) save this haskell file and your AOC input file in some directory on your computer
+-- 3) rewrite the "main" function with the location of your AOC input file
+-- 4) rewrite "print contents" in the "main" function to use the function(s) you've made to process the input file ("contents") from that day correctly
+-- 5) run Command Prompt, go to the directory of your files (with "cd" command) and run the command "ghci AOC2025.hs"
+-- 6) run command "main"
+-- 7) if your functions are correct, you'll get the correct answer!
