# Proposing an Index

First step in the basket creation process is for an index publisher to propose a new index. The proposer calls `proposeBasketLicense` on the factory contract. This contract takes the following inputs:

|               |                                                                         |
| ------------- | ----------------------------------------------------------------------- |
| `tokenName`   | Full name of the basket token                                           |
| `tokenSymbol` | Symbol for the basket token                                             |
| `tokens`      | array of token contract addresses that will be included in the index    |
| `weights`     | the amount of tokens (uint256) in 1 basket token upon basket's creation |

The protocol will assign an `idNumber` to the proposal.
