 ## How to play
 
-### General
+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 unmutable keybinds.  
-You will find some more infos about the Rotation System and the scoring in the **INFO** section of the main menu.  
-If you want to know more details about the generation and classification of polyominoes, [check the documentation](/doc/)!

 ## 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 run text``
+``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.

 ## Score calculation
 
-- For every position soft dropped, add 1 to the score
-- For every position hard dropped, add 2 to the score
+- When locking a piece, add 1 to the score if it is due to lock delay, or 10 if it was hard dropped.
 - When clearing one line, add 100 to the score, 200 for 2 lines, 400 for 3 lines, 800 for 4 lines, 1600 for 5 lines, etc.
 - If the line clear is a spin, count the score like a normal clear of 2x more line (200 for 1-line spin, 800 for 2, 3200 for 3, etc.)
 - When performing a spin, a mini spin, or clearing 4 or more lines, B2B is activated, every subsequent line clear that is a spin, a mini spin, or clear 4 or more lines, scores twice as much
+
+## Grade calculation
+
+Grade is an alternate system to line clears.
+
+- Each time a piece is dropped, 1 point is added to the total.
+- For each cleared line, 1 point is added to the total.
+
+The only exception occurs when the total ends in '99', a line must be cleared to progress.
+When this line is cleared, the point of the piece is also counted towards the total.
+
+## 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.
