-# Advanced Vehicles
-Adds smart different cars (passenger cars, trucks, buses, service). 
+# Advanced Vehicles 1.0.0-Release Candidate #1
+
+## Description
+------------------------------
+Adds smart different cars (passenger cars, trucks, buses, service). This mod introduces little API to register cars with analogical parameters that use the mod (see *API Documentation)
+
+## API Documentation
+------------------------------
+###adv_vehicles.register_vehicle(vehicle_name, vehicle_properties, vehicle_item)
+--Registers a vehicle in the game as an entity and an item spawner for it.
+
+*vehicle_name* is entity string.
+*vehicle_properties* is a table with following fields:
+     hp_max,
+     mass,   is a property that sets a value of vehicle mass in tons. Necessary for calculating of the gravity.
+     max_vel,  measured in metres in sec.
+     cbox,  is collision box.
+     model,
+     textures,
+     seats, is a table that contains a data about each seat (busy_by, pos fields). Key should be string containing a sort of seat (driver or passenger).
+     player_eye_offset, is pos table
+*vehicle_item* is a table with item spawner data. Fields: description, inv_image, craft_recipe.
+
+###adv_vehicles.rotate_point_around_other_point(circle_center_pos, rotating_point_pos, fixed_point_yaw, current_point_yaw)
+--This method implements affine transformation of a point *rotating_point_pos* rotation along a circle with *circle_center_pos* center.
+
+*circle_center_pos* is position table.
+*rotating_point_pos* is position table.
+*fixed_point_yaw* is the last fixed yaw of a vehicle (saving in self.fixed_veh_rotate_angle).
+*current_point_yaw* is current yaw of a vehicle.
+
+###adv_vehicles.attach_player_to_veh(player, vehicle, seated, model, animation)
+--Attaches a player to the vehicle.
+
+*player* is PlayerObjectRef.
+*vehicle* is ObjectRef.
+*seated* is "driver" or "passenger" keys depending on which field in *seats_list* used.
+*model* is vehicle model (.b3d format).
+*animation* is a table with x, y fields
+
+###adv_vehicles.detach_player_from_veh(player, vehicle, seated, model, animation)
+--Opposite to *adv_vehicles.attach_player_to_car*. Detaches a player from the car and the same arguments.
+
+###adv_vehicles.pave_vector(vehicle, vect_length, old_yaw)
+--Paves the vector from '0' point relatively to the car origin towards to *vect_length*.
+*old_yaw* is a integer value that saving in self.fixed_veh_rotate_angle.
+This method should be caused continuously per 0.1 second to recalculate the car direction.
+
+###adv_vehicles.rotate_collisionbox(vehicle, yaw)
+This method is WIP and doesnt work properly currently.
+
+*This documentation is in working progress.*
