-### Required Crates
+### Included Crates and Modules
 
-This tutorial applies to the Rust implementation of the Casper NFT standard, which requires the following Casper crates:
+The contract implementation starts by importing the following essential Casper crates:
 
 - [casper_contract](https://docs.rs/casper-contract/latest/casper_contract/index.html) - A Rust library for writing smart contracts on Casper networks
 - [casper_types](https://docs.rs/casper-types/latest/casper_types/) - Types used to allow the creation of Wasm contracts and tests for use on Casper networks
 
-Here is the code snippet that imports those crates:
-
-```rust
-use casper_contract::{
-    contract_api::{
-        runtime::{self, call_contract, revert},
-        storage::{self},
-    },
-    unwrap_or_revert::UnwrapOrRevert,
-};
-use casper_types::{
-    contracts::NamedKeys, runtime_args, CLType, CLValue, ContractHash, ContractPackageHash,
-    EntryPoint, EntryPointAccess, EntryPointType, EntryPoints, Key, KeyTag, Parameter, RuntimeArgs,
-    Tagged,
-};
-```
-
-**Note**: In Rust, the keyword `use` is like an include statement in C/C++.
-
 The contract code defines additional modules in the `contract/src` folder:
 
-```rust
-mod constants;
-mod error;
-mod events;
-mod metadata;
-mod modalities;
-mod utils;
-```
-
 - `constants` - Constant values required to run the contract code
 - `error` - Errors related to the NFT contract
 - `events` - A library for contract-emitted events
-- `metadata` - Module handling the contract's metadata and corresponding dictionary
+- `metadata` - A module handling the contract's metadata and corresponding dictionary
 - `modalities` - Common expectations around contract usage and behavior
 - `utils` - Utility and helper functions to run the contract code

 ### Contract Entrypoints
 
-This section briefly explains the essential entrypoints used in the Casper NFT contract. To see their full implementation, refer to the [main.rs](https://github.com/casper-ecosystem/cep-78-enhanced-nft/blob/dev/contract/src/main.rs) contract file. For further questions, contact the Casper support team via the [Discord channel](https://discord.com/invite/casperblockchain). The following entrypoints are listed as they are found in the code.

+- `mint` (with *OwnerReverseLookupMode* set to *Complete*)
+- `transfer` (with *OwnerReverseLookupMode* set to *TransfersOnly*)
+- `balance_of`
+- `is_approved_for_all`
+- `owner_of`
+- `metadata`

 ## Installing the Contract
 
 Installing the enhanced NFT contract to global state requires using a [Deploy](../../../../developers/cli/sending-deploys.md). But before proceeding with the installation, verify the network state and the status of the account that will send the installation deploy.
