  *  Group together arbitrary ERC20, ERC721 and ERC1155 tokens into a single bundle.

- *  This bundle of tokens is a generic list of tokens that can have multiple use cases,
- *  such as mapping to an NFT, or put in an escrow, etc.
+ *  The `Token` struct is a generic type that can describe any ERC20, ERC721 or ERC1155 token.
+ *  The `Bundle` struct is a data structure to track a group/bundle of multiple assets i.e. ERC20,
+ *  ERC721 and ERC1155 tokens, each described as a `Token`.
+ *
+ *  Expressing tokens as the `Token` type, and grouping them as a `Bundle` allows for writing generic
+ *  logic to handle any ERC20, ERC721 or ERC1155 tokens.
