+//! # Nonfungible Pallet
+//!
+//! The Nonfungible pallet provides functionality for handling nonfungible collections and tokens.
+//!
+//! - [`Config`]
+//! - [`NonfungibleHandle`]
+//! - [`Pallet`]
+//! - [`CommonWeights`]
+//!
+//! ## Overview
+//!
+//! The Nonfungible pallet provides functions for:
+//!
+//! - NFT collection creation and removal
+//! - Minting and burning of NFT tokens
+//! - Retrieving account balances
+//! - Transfering NFT tokens
+//! - Setting and checking allowance for NFT tokens
+//! - Setting properties and permissions for NFT collections and tokens
+//! - Nesting and unnesting tokens
+//!
+//! ### Terminology
+//!
+//! - **NFT token:** Non fungible token.
+//!
+//! - **NFT Collection:** A collection of NFT tokens. All NFT tokens are part of a collection.
+//! Each collection can define it's own properties, properties for it's tokens and set of permissions.
+//!
+//! - **Balance:** Number of NFT tokens owned by an account
+//!
+//! - **Allowance:** NFT tokens owned by one account that another account is allowed to make operations on
+//!
+//! - **Burning:** The process of “deleting” a token from a collection and from
+//! an account balance of the owner.
+//!
+//! - **Nesting:** Setting up parent-child relationship between tokens. Nested tokens are inhereting
+//! owner from their parent. There could be multiple levels of nesting. Token couldn't be nested in
+//! it's child token i.e. parent-child relationship graph shouldn't have cycles.
+//!
+//! - **Properties:** Key-Values pairs. Token properties are attached to a token. Collection properties are
+//! attached to a collection. Set of permissions could be defined for each property.
+//!
+//! ### Implementations
+//!
+//! The Nonfungible pallet provides implementations for the following traits. If these traits provide
+//! the functionality that you need, then you can avoid coupling with the Nonfungible pallet.
+//!
+//! - [`CommonWeightInfo`](pallet_common::CommonWeightInfo): Functions for retrieval of transaction weight
+//! - [`CommonCollectionOperations`](pallet_common::CommonCollectionOperations): Functions for dealing
+//! with collections
+//!
+//! ## Interface
+//!
+//! ### Dispatchable Functions
+//!
+//! - `init_collection` - Create NFT collection. NFT collection can be configured to allow or deny access for
+//! some accounts.
+//! - `destroy_collection` - Destroy exising NFT collection. There should be no tokens in the collection.
+//! - `burn` - Burn NFT token owned by account.
+//! - `transfer` - Transfer NFT token. Transfers should be enabled for NFT collection.
+//! Nests the NFT token if it is sent to another token.
+//! - `create_item` - Mint NFT token in collection. Sender should have permission to mint tokens.
+//! - `set_allowance` - Set allowance for another account.
+//! - `set_token_property` - Set token property value.
+//! - `delete_token_property` - Remove property from the token.
+//! - `set_collection_properties` - Set collection properties.
+//! - `delete_collection_properties` - Remove properties from the collection.
+//! - `set_property_permission` - Set collection property permission.
+//! - `set_token_property_permissions` - Set token property permissions.
+//!
+//! ## Assumptions
+//!
+//! * To perform operations on tokens sender should be in collection's allow list if collection access mode is `AllowList`.
