+## Bullets
+
+We use differents types of bullets in the game. Each type of bullet has its own characteristics.
+Bullets are defined in the `bullets.json` file.
+
+### Json structure
+
+We use the following structure to define bullets:
+
+```json
+{
+    "bullets": [
+        {
+            "id": "classic",
+            "velocity": {
+                "speedX": 120,
+                "speedY": 0
+            },
+            "spritePath": "assets/R-TypeSheet/WaterBullets.png",
+            "soundPath": "assets/Audio/Sounds/laser.ogg",
+        },
+        {
+            "id": "perforant",
+            "velocity": {
+                "speedX": 400,
+                "speedY": 0
+            },
+            "spritePath": "assets/R-TypeSheet/FireBullets.png",
+            "soundPath": "assets/Audio/Sounds/laser2.ogg",
+        }
+    ]
+}
+```
+
+It is composed of an array of bullets. Each bullet has its own id and its own characteristics.
+
+### Characteristics
+
+- `id`: The id of the bullet. It is used to identify the bullet in the game.
+- `damage`: The damage of the bullet. It is used to damage the enemies.
+- `health`: The health of the bullet. It is used to destroy the bullet when it collides with an enemy.
+- `velocity`: The velocity of the bullet. It is used to move the bullet.
+- `physics`: The physics of the bullet. It is used to move the bullet.
+- `waitTimeBullet`: The wait time of the bullet. It is used to wait before shooting again.
+- `collisionRect`: The collision rectangle of the bullet. It is used to detect collisions with enemies.
+- `spritePath`: The sprite path of the bullet. It is used to display the bullet.
+- `soundPath`: The sound path of the bullet. It is used to play the sound of the bullet.
+- `spriteRect`: The sprite rectangle of the bullet. It is used to display the bullet.
+- `animRect`: The animation rectangle of the bullet. It is used to display the bullet.
+
+
+### Physics
+
+Physics is represented by an array of strings. Each string represents a physics. You can put as many physics as you want. So far, we have the following physics:
+- `zigzag`: The bullet moves in a zigzag way.
+- `boncing`: The bullet bounces on the top and bottom of the screen.
+
+
+```json
+{
+    "bullets": [
+        {
+            "id": "perforant",
+            "physics": [
+                "zigzag"
+            ]
+        }
+    ]
+}
+```
+
+### Bullet types
+
+For now, we have 4 types of bullets:
+- `classic`: The classic bullet.
+- `fast`: The fast bullet.
+- `bounce`: The bouncing bullet.
+- `perforant`: The perforant bullet.
+
+To add a new bullet type, you have to add it in the `missileTypes_e` enum in the `Missile.hpp` file. Then, you have to add it in the `bulletKeyMap` map in the `EventsSystems.cpp` file.
