 # Container
+
+Every [`FComponent`](/api/2d/classes/FComponent) in `@fibbojs/2d` has a `container` property that corresponds to the [PixiJS Container](https://pixijs.com/8.x/guides/components/containers) that will be used to render the component.
+
+This is either a [Graphics](https://pixijs.com/8.x/guides/components/graphics) (for squares, circles,...) or a [Sprite](https://pixijs.com/8.x/guides/components/sprites) (basically an image) depending on the component.
+
+Unless you have a good reason to do so, you should not modify the `container` directly, but use the provided methods instead.

 # Polygons
+
+Fibbo provides a simple way to create polygons in 2D.
+
+For now, only 2 types of polygons are supported: squares and circles.
+
+## Squares
+
+To create a square, you can use the `FSquare` class. Here is an example:
+
+```typescript
+import { FSquare } from '@fibbojs/2d'
+
+const square = new FSquare({
+  position: { x: 0, y: 5 },
+  scale: { x: 1, y: 1 },
+})
+```
+
+This will create a square with a size of `1` at the position `(0, 5)`.
+
+## Circles
+
+To create a circle, you can use the `FCircle` class. Here is an example:
+
+```typescript
+import { FCircle } from '@fibbojs/2d'
+
+const circle = new FCircle({
+  position: { x: 0, y: 5 },
+  scale: { x: 1, y: 1 },
+})
+```
+
+This will create a circle with a radius of `1` at the position `(0, 5)`.

 # Sprites
+
+Sprites are the most common way to display objects in a 2D game. They are essentially 2D images that can be moved, rotated, and scaled in the scene.
+
+## Creating a sprite
+
+To create a sprite, you can use the `FSprite` class. Here is an example:
+
+```typescript
+import { FSprite } from '@fibbojs/2d'
+
+const sprite = new FSprite({
+  path: 'path/to/image.png',
+  position: { x: 0, y: 5 },
+  scale: { x: 1, y: 1 },
+})
+```
+
+This will create a sprite with the image located at `path/to/image.png` at the position `(0, 5)`.
