 ### 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](../../../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.

This entrypoint can only be called once when the contract is installed on the network

+**IMPORTANT**: The following entrypoints return data using `runtime::ret`, which is useful mainly if the entrypoint caller is a contract:
+
+- `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](https://docs.casper.network/developers/dapps/sending-deploys/). But before proceeding with the installation, verify the network state and the status of the account that will send the installation deploy.
