 ## Manual build
 
 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.  
 
+If you want to contribute or are simply curious, you can check the [wiki](https://git.ale-pri.com/TetrisNerd/jminos/wiki)!

 If you need to change the toolchain (for example using gcc):  
 ``xmake f --toolchain=gcc``
 
+If you want to build for another platform (for example with mingw):  
+``xmake f -p mingw``
+
 ### Run the project
 
 ``xmake run``  
-Note that the program will generate the polyomino files for you the first time. This lasts several minutes so it only does it up to size 10. If you want to use the full range up to size 15, you will need to uncomment the ``#define`` at line 13 of file ``src/GraphicalUI/Settings.h``.
+
+The program will generate the polyomino files for you if you don't have them.
+As this is a lengthy process, debug mode limits pieces size to 10.
+To switch between debug and release mode:  
+``xmake f -m debug``  
+``xmake f -m release``
 
 If for some reasons you wanna run the command line version:  
+``xmake build text``  
 ``xmake run text``  
+The command line version is **not** updated.
 
-### Create a release version (xmake packaging ???)
+### Package the project
+
+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}``.

 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).

 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.

 The only exception occurs when the total ends in '99', a line must be cleared to progress.

+## Pieces distribution
+
+A bag is an object which contains a set of pieces.
+The principle of a bag generator is to put every available pieces into a bag and take them out one by one until the bag is empty, to then start with a new full bag.
+It's a way to have equal distribution of pieces while still allowing for a random order of pieces.
+
+The game has 3 modes of pieces distribution:
+
+1. Default. The simplest of them, all selected pieces are put in a single bag.
+2. Uniformous. The pieces are now separated by size and put in different bags. Each size will now appear as often as any other.
+3. Custom. The pieces are once again separated by size, but now the player specifies how likely each size is to appear.
+
+Both system 2 and 3 uses a system analogous to a bag to determine which size of piece to take next.
