 This package contains tools that are not yet final and may change or contain unknown bugs, and are pending more testing or reviews.
 
-## Cashmap
-
-A hashmap-like structure, that allows iteration with paging over keys without guaranteed ordering.
-An example use-case for such a structure is if you want to contain a large amount of votes, deposits, or bets and iterate over them at some time in the future.
-Since iterating over large amounts of data at once may be prohibitive, this structure allows you to specify the amount of data that will
-be returned in each page.
-
-This structure may also be used as a hashmap structure without the fancy bells and whistles, though gas-costs will be more expensive than simple storage.
-
-### Usage
-
-#### Initialization
-
-You can open/initialize the cashmap directly using 
-
-```rust
-let mut storage = MockStorage::new();
-let mut cmap = CashMap::init(b"cashmap-name", &mut storage);
-```
-
-#### Access pattern
-
-Todo: improve this section
-
-```rust
-let foo1 = Foo {
-    string: "string one".to_string(),
-    number: 1111,
-};
-
-cmap.insert(b"key1", foo1.clone())?;
-let read_foo1 = cmap.get(b"key1").unwrap();
-cmap.remove(b"key1")?;
-```
-
-### Todo
-
-Generalize keys to allow any hashable type, not just &[u8]

 ## Max heap storage
 
 A "max heap store" is a storage wrapper that implements a binary tree maxheap data structure.
