 In general you can use Merkle Trees to proof / validate that a specific element is available at a specific index within an array (block, ...) - without the need to load the elements themselves.   
 
 ## Usage Example
-
 ```sh
-
 deno run https://deno.land/x/merkletrees/usage-example.ts
-
 ```
 
 ```ts  
-
 import { MerkleTree, Helper } from "https://deno.land/x/merkletrees/mod.ts"
 
 const exampleArray = ["dog", "horse", "cow", "chicken"]

 const merkleTree = new MerkleTree(exampleArray)
