-## MorphoChainlinkOracleV2Factory
-
-The `MorphoChainlinkOracleV2Factory` is a factory that deploys `MorphoChainlinkOracleV2` instances.
-
-The factory facilitates the creation and indexing of `MorphoChainlinkOracleV2` oracles. This factory contract streamlines the process of deploying new oracles, catering to various market pairs without the need to deploy individual contracts manually for each pair.

-### Deploy an Oracle
+**Warning:** If there is an ERC4626-compliant vault for `baseVault` or `quoteVault`, the `baseTokenDecimals` or `quoteTokenDecimals` are still the decimals of the underlying asset of the vault, and not the decimals of the Vault itself.
+E.g: for a MetaMorpho WETH vault, as `baseVault`, the `baseTokenDecimals` is 18 as WETH has 18 decimals.
