+## Examples
+
+If you prefer to read example code immediately, you can find example scenes in [`Scenes`](Scenes) folder.
+
+## Model classes
+
+* [`Vertex.cs`](Model/Vertex.cs)
+	+ Basically a `Vector2` point, but is aware of the polygon context it resides (neighbours, segments, edges, polygon, bisector, normal).
+* [`Segment.cs`](Model/Segment.cs)
+	+ Segment of two `Vector2` point. Carries out basic geometry features (point distance, point containment, segment intersection).
+* [`Edge.cs`](Model/Edge.cs)
+	+ Edge of two `Vertex` in a polygon (a special `Segment` subclass). Likewise vertices, this model is also aware of the polygon context it resides (neighbours, segments, edges, polygon, perpendicular, normal).
+* [`Polygon.cs`](Model/Edge.cs)
+	+ The role player, it really **embodies mostly every feature of this library**. Basically a polygon made of vertices.
+	+ Can be created with point array, transforms, [`PolygonSource`](Components/PolygonSource.cs). Further polygons can be embedded into recursively. Vertices, edges, polygons can be enumerated (recursively).
+	+ Area, winding direction, centroid are being calculated. Also carries the basic geometry features (point containment, line-, segment-, polygon intersection and more).
+	+ Using library modules, it implements polygon offset (outline), union polygon (polygon clipping), basic mesh triangulation. It implements conversion to both [Clipper](https://github.com/eppz/Clipper) and [Triangle.NET](https://github.com/eppz/Triangle.NET), so you can implement further integration with those (awesome) libraries.
 
 ## [`Geometry.cs`](Geometry.cs)
 
-The basic 2D geometry algorithm collection is implemented in this static base class.
+Most of the basic 2D geometry algorithm collection is implemented in this static base class. You can (mostly) **use them with Unity `Vector2` types directly**, so (almost entirely) without the model classes introduced above.
 
 * **Point**
 	+ `bool ArePointsEqualWithAccuracy(Vector2 a, Vector2 b, float accuracy)`
