+Geometry classes can be also created by these static methods:
 
-Every geometry class has these functions:
+* `fromJson(string $geoJson, int $srid = 0)` - Creates a geometry object from a [GeoJSON](https://en.wikipedia.org/wiki/GeoJSON) string.
+* `fromWkt(string $wkt, int $srid = 0)` - Creates a geometry object from a [WKT](https://en.wikipedia.org/wiki/Well-known_text_representation_of_geometry).
+* `fromWkb(string $wkb, int $srid = 0)` - Creates a geometry object from a [WKB](https://en.wikipedia.org/wiki/Well-known_text_representation_of_geometry#Well-known_binary).
+
+## Available geometry class methods
 
 * `toArray()` - Serializes the geometry object into a GeoJSON associative array.
 * `toJson()` - Serializes the geometry object into an GeoJSON string.
-* `fromJson(string $geoJson)` - Deserializes a geometry object from a GeoJSON string. (static method) 
 * `toFeatureCollectionJson()` - Serializes the geometry object into an GeoJSON's FeatureCollection string.
+* `toWkt()` - Serializes the geometry object into a WKT.
+* `toWkb()` - Serializes the geometry object into a WKB.
 * `getCoordinates()` - Returns the coordinates of the geometry object.
