 - **`state`**, **`setState`** and **`initialState`** are exactly the same with native React's `useState` hook;
-- **`historyCapacity`** - amount of history entries that hold by storage;
-- **`initialHistory`** - if defined it will be used as initial history value, otherwise history will equals `[ initialState ]`.  
+- **`capacity`** - amount of history entries held by storage;
+- **`initialHistory`** - if defined it will be used as initial history value, otherwise history will equal `[ initialState ]`.  
 Initial state will not be pushed to initial history.  
-If entries amount is greater than `historyCapacity` parameter it wont be modified on init but will be trimmed on next `setState`;

 - **`stateHistory`** - an object containing history state:
-    - **`history`**_`: S[]`_ - an array holding history entries. _I will have the same ref all the time so pe careful with that one!_;

     In case `position` is non-negative ot will count elements from beginning.
     Negative `position` will cause elements counting from the end, so `go(-2)` equals `go(history.length - 1)`;
