+# Elite Four
 
+A small game I made for four of my friends.
+Each of them has a dedicated mini-game, and the goal is to beat them all.

+# Play the game
 
+### Download an executable file
 
+To play the game, you can download it in the [Releases](https://github.com/Hvrnbi/elite-four/releases) section.
+- If you're using Windows, you can download the .exe file.
+- If you're using linux, you can try the other executable, it was tested on Debian 13 with an amd64 architecture.
+- If you're using something else, you can see the **run from the Python file** section or the **building** section.
+
+### Run the game from the Python file
+
+To run the game from the main.py file, you have to
+
+- clone this repo with ```git clone https://github.com/Hvrnbi/elite-four```,
+- go to the directory of the game with ```cd elite-four```,
+- create a Python virtual environment with ```python3 -m venv .venv``` on Unix, ```python -m venv .venv``` on Windows,
+- install the dependencies with ```.venv/bin/pip install -r requirements.txt``` on Unix, ```.venv\Scripts\pip install -r requirements.txt``` on Windows,
+- and finally run the game with ```.venv/bin/python3 main.py``` or ```.venv\Scripts\python main.py```.
+
+### Build the game from source
+
+To build the game from source, do the steps above (without running the game) and run ```.venv/bin/pip install pyinstaller```.
+You should now be able to run ```.venv/bin/pyinstaller main.py --add-data="images:images" --add-data="audio:audio" --hidden-import='PIL._tkinter_finder' --onefile```, and the game should be built !

 # Thanks
 
+This game is dedicated to Mister C, Mister E, Miss N and Miss W 💜
+
+The song from the Miss W"s game was performed by me and inspired by [the Scottish of Ruz Reor](https://youtu.be/_QP1e3a9Jhc)
+
 All the pictures used for the Mister C's game are listed in [this file](PICTURES-CREDITS.md).
 
 I used the website [flagcolorcodes](https://www.flagcolorcodes.com/search/france) for the color of the flags.
+
+Thank you for your interest in this project made with ❤️ by a human for his friends.
