-This game has been tested on and built on Windows 11 and WSL2 Ubuntu only.

 ## How to play
 
+Choose which pieces you want to play with and stack them up until you either win or top out!  
+Make full lines to make them dissapear.  
+Use the different spins to kick the pieces in spot you couldn't imagine were attaignable!  
+Each gamemode has its own objective, but you can play as you wish.  
+
 You can see and change in-game keybinds in the **SETTINGS** section of the main menu!  
 All of in-menu navigation is done with the **arrow keys**, the **Enter key** and the **Escape key**. Theses are unchangeable keybinds.  
-You will find more infos about the Rotation System, the scoring system, or the different pieces type in the **INFO** section of the main menu.

 This project uses xmake for compiling, xmake is cross-platform and works in most OS, xmake also automatically install supported librairies.  
 To be able to build this project, you need to [have xmake installed](https://xmake.io) and have a compiler with C++20 compatibility.

 ### Package the project
 
-// TODO when the game is finished //
+To package the executable manually properly, follow theses steps:  
+
+1. Clone the project into a new folder.
+2. If you already have all 15 pieces files, copy them over to the ``data/pieces`` folder, else you will be generating them at the next step.
+3. Go into release mode (``xmake f -m release``) and run the project once (``xmake`` and ``xmake run``). This is to generate the default config files, close the game immediately after it started.
+4. Make a new folder named ``jminos`` and copy the executable (should be located somewhere like ``build/linux/x86_64/release/graph``) as well as the ``data/pieces`` and ``data/config`` folders.
+5. Zip the newly created ``jminos`` folder into a file named ``jminos_{platform}``.

 ## Pieces
 
-If you don't know what a polyomino is, check [this other file](Pieces_representation.md#what-are-polyominoes).
+_Note: the current algorithm has been adapted to use file compression. There is currently no documentation on how the compression work, but you can check the code in the [src/Common](https://git.ale-pri.com/TetrisNerd/jminos/src/branch/main/src/Common) folder._
 
 Generating polyominoes of size n is exponential in regard to n. Because of this, we will store the pieces beforehand and load them upon launching the game.
 
-We want the pieces to be always sorted in the same order, always attributed the same block type, and always set at the same spawn position, no matter how they were generated. We also want them to be separated in 3 categories : convex, not convex but without a hole, and with a hole. Theses problematics are already resolved internally, but will be calculated before storage as to not need extra calculcations upon load (except for the block type which is trivially computed).

Theses problematics are already solved internally, but will be calculated before storage as to not need extra calculcations upon load (except for the block type which is trivially computed).
 
 Pieces are stored in binary files. Each file simply contains every polyomino of one size, one after the other. Since each file contains all polyominoes of the same size, we know how much stuff to read and don't need delimiters. We know we've read all pieces simply when we reach the end of file character.

     and 3 bytes to store the number of the piece (allows number up to 16M, size 15 has 6M pieces).
 
-The current file format version is 11.
-If the file starts with a number lower than that, it will be regenerated upon launching the game.
