+Nitro is currently licensed under a [Business Source License](./LICENSE), similar to our friends at Uniswap and Aave, with an "Additional Use Grant" to ensure that everyone can have full comfort using and running nodes on all public Arbitrum chains.
+
+The Additional Use Grant also permits the deployment of the Nitro software, in a permissionless fashion and without cost, as a new blockchain provided that the chain settles to either Arbitrum One or Arbitrum Nova. 
+
+For those that prefer to deploy the Nitro software either directly on Ethereum (i.e. an L2) or have it settle to another Layer-2 on top of Ethereum, the [Arbitrum Expansion Program (the "AEP")](https://docs.arbitrum.foundation/assets/files/Arbitrum%20Expansion%20Program%20Jan182024.pdf) was recently established. The AEP allows for the permissionless deployment in the aforementioned fashion provided that 10% of net revenue (as more fully described in the AEP) is contributed back to the Arbitrum community in accordance with the requirements of the AEP.
