 ### `dynamic_map`
 
-`cuco::dynamic_map` links together multiple `cuco::static_map`s to provide a hash table that can grow as key-value pairs are inserted. It currently only provides host-bulk APIs. See the Doxygen documentation in `dynamic_map.cuh` for more detailed information.
+`cuco::dynamic_map` links together multiple `cuco::static_map`s to provide a hash table that can grow as key-value pairs are inserted. It supports `insert`, `insert_or_assign`, `erase`, `find`, `contains`, and `retrieve_all` operations via host-bulk APIs with kernel-based implementations for optimal performance. See the Doxygen documentation in `dynamic_map.cuh` for more detailed information.
