+The Gridify library adds the below extension methods to `IQueryable` objects.
 
 All Gridify extension methods can accept [GridifyQuery](./gridifyQuery.md) and [GridifyMapper](./gridifyMapper.md) as a parameter.

 If you want to use Gridify extension methods on an `IEnumerable` object, use `.AsQueryable()` first.
