-### Hub Chain Requirements
+### Deployment Mode Requirements
 
-For hub chain deployments on Solana, the token can be either an SPL or Token2022. Hub chain tokens do not require additional configuration, such as setting the mint authority.
+The NTT CLI supports two deployment models: **Hub-and-Spoke** and **Burn-and-Mint**.  
+For a detailed explanation of these models, see the [Deployment Models](/docs/learn/messaging/native-token-transfers/deployment/){target=\_blank} page.

+#### Hub-and-Spoke
 
-### Burning Mode Requirements
+No additional configuration is required for hub-and-spoke deployments. Tokens retain their original mint authority, so the steps below are not necessary. You can [generate a new NTT program key pair](/docs/build/contract-integrations/native-token-transfers/deployment-process/deploy-to-solana/#generate-ntt-program-key-pair) and [deploy the NTT program](/docs/build/contract-integrations/native-token-transfers/deployment-process/deploy-to-solana/#__tabbed_2_2) directly.
 
-In burning mode, tokens require their mint authority to be assigned to the NTT program. This allows the NTT Manager to mint and burn tokens as needed during cross-chain transfers. 
+#### Burn-and-Mint
 
-All necessary steps for configuring burning mode, including mint authority setup, are explained in the sections below.
+For burn-and-mint deployments, you must configure the token's mint authority to enable cross-chain transfers. To complete the required setup, follow the steps in the following sections.
