+# File Parser Specification
+
+For the Project, I wanted to challenge myself, I decided to do my own file parser with my own specification that would
+have the special objective of being really small.
+
+## The File format
+
+The file would use the .level file extension.
+
+The file can contain anything, the used data is enclosed between a header and a footer.
+This could be used to add: musics, images and other stuff in the level file itself 
+
+Only one Header and One Footer should be present in the file.
+The parser will only read the first one it finds so to avoid problem, it is best practise to put the
+level data at the top of the file.
+
+- The HEADER will be defined by the succesion of the characters 'S', 'M' then 'S' 
+- The FOOTER will be defined by the succesion of the characters 'S', 'M', then 'E'
+- The bytes in between are the level data
+  - byte 1: Width of the map
+  - byte 2: Height of the map
+  - bytes 3 -> Width * Height (+1 if Width * Height % 8 is not 0)
+  - byte after Map Data: Pieces amount
+  - for each pieces
+    - 1 byte: size of the piece
+      - 4 first bits : width
+      - 4 last bits: height
+    - next bytes -> Width * Height (+1 if Width * Height % 8 is not 0)
+
+### Saved file
+
+For saved file, the extension will be .slevel
+The only difference is that at the end of the map data (after the pieces and before the
+Footer. there will be the position of each pieces from their top-left corner in the map.
+following this pattern for each pieces
+
+  - 'F' and 'L' on 2 bytes for floating positions when the piece is not placed
+  - x and y on 2 bytes for position if the piece is placed
+
+## Known Limitation
+
+1) by putting the piece size on one byte. We limit the maximum piece size to 15 x 15 (1111 | 1111)
+I don't think we will ever need a piece larger than 5x5 so this is clearly a feature, not a bug! :-)
+We might use the same methods for the pieces positions but there could be a posibility to have
+larger map if I use 2 bytes for the positions.
