 ### Overview
-Component for manage node positions. Very simple implementation for nodes with equal size
+Component for manage node positions. Static grid have constant node size, so it possible to calculate node positions before placement. Nodes can be placed with gaps. Static grid can shift elements on add/remove functions.
 
 ### Setup
-Create  component with druid: `grid = druid:new_grid(parent_node, prefab_node, max_in_row_elements)`
+Create  component with druid: `grid = druid:new_static_grid(parent_node, prefab_node, max_in_row_elements)`
 
 ### Notes
-- Grid on _adding elements_ will setup parent to _parent_node_
+- On _add node_ grid will set node parent to _parent_node_
 - You can get array of position of every element for setup points of interest in scroll component
 - You can get size of all elements for setup size in scroll component
-- You can adjust anchor and border between elements
-- _Prefab node_ in component init used to get grid item size
+- You can also bind the grid to the scroll component for auto resize scroll content size

+
+### Overview
+Component for manage node positions with different node sizes. Unlike Static Grid, Dynamic Grid can place nodes only in one row or in one column. Dynamic Grid can't have gaps between elements - you will get error, if try spawn element far away from others. Dynamic Grid should have __West__, __East__, __South__ or __North__ pivot (vertical or horizontal element placement)
+
+### Setup
+Create  component with druid: `grid = druid:new_dynamic_grid(parent_node)`
+
+Check the _parent_node_ have correct pivot point. You will get the error otherwise.

+- You can point *position_function* for animations with _static_grid:set_position_function(node, pos)_ callback. Default - *gui.set_position()*
+- First node placed at Grid pivot point. Other nodes placed nearby of other nodes.
+- On *add/remove* nodes always shifted. You can point the shift side in this functions (*is_shift_left* boolean argument)
