 ## Usage
 
-When deployed a Möbius contract will emit a `Message` that is an arbitrary hex encoded string. This message is signed to make withdrawals from the contract. 
+When deployed a Möbius contract will emit a `RingMessage` that is an arbitrary hex encoded string. This message is signed to make withdrawals from the contract. 
 
-Orbital can be used to generate all data needed to deposit and withdraw from a Möbius smart contract. Providing you have the `Message` value data can be generated as follows. In this example the hex encoded string is given as `666f6f62617262617a`. A ring size of 2 is generated.

 This generates JSON containing complete data required to deposit and withdraw. If you are just evaluating Möbius this is all you need to deposit into a contract and then make withdrawals once the ring is full.

 Beyond evaluation it is likely that you will want to first generate public/private keypairs and distribute this to allow signatures to be created separately. To create a public/private keypairs for a ring size of `2` use
