 # Morpho Blue Oracles
 
-
 Morpho Blue Oracles are contracts that can be used as oracles for markets on [Morpho Blue](https://github.com/morpho-org/morpho-blue).
 The oracles implement the `IOracle` interface defined in [`IOracle.sol`](https://github.com/morpho-org/morpho-blue/blob/main/src/interfaces/IOracle.sol#L9): they return the price of 1 asset of collateral token quoted in 1 asset of loan token.

-## Getting Started
+## WstETH/stETH Exchange Rate Adapter
 
-Install dependencies: `forge install`
+A specific implementation, the `WstEthStEthExchangeRateChainlinkAdapter`, provides the exchange rate between wstETH and stETH.
 
-In a `.env` file, set `ETH_RPC_URL` to the URL of an Ethereum provider.
+Deployed on Ethereum Mainnet, this adapter can be found on Ethereum Mainnet at the address [0x905b7dAbCD3Ce6B792D874e303D336424Cdb1421](https://etherscan.io/address/0x905b7dabcd3ce6b792d874e303d336424cdb1421#code).

+## MorphoChainlinkOracleV2Factory
+
+The `MorphoChainlinkOracleV2Factory` is a factory that deploys `MorphoChainlinkOracleV2` instances.
+
+The factory facilitates the easy creation and indexing of `MorphoChainlinkOracleV2` oracles. This factory contract streamlines the process of deploying new oracles, catering to various market pairs without the need for deploying individual contracts manually for each pair.
+
+### Usage
+
+The Ethereum Mainnet address of this factory is [0x3A7bB36Ee3f3eE32A60e9f2b33c1e5f2E83ad766](https://etherscan.io/address/0x3a7bb36ee3f3ee32a60e9f2b33c1e5f2e83ad766#code).
+
+To create a new `MorphoChainlinkOracleV2` oracle using the factory, call the `createMorphoChainlinkOracleV2` function with the following parameters:
+
+- `baseVault`: The ERC4626 token vault for the base asset.
+- `baseVaultConversionSample`: A sample size for converting base vault units.
+- `baseFeed1`, `baseFeed2`: Chainlink-interface-compliant data feeds for the base asset.
+- `baseTokenDecimals`: Decimal precision of the base asset.
+- `quoteVault`: The ERC4626 token vault for the quote asset.
+- `quoteVaultConversionSample`: A sample size for converting quote vault units.
+- `quoteFeed1`, `quoteFeed2`: Chainlink-interface-compliant data feeds for the quote asset.
+- `quoteTokenDecimals`: Decimal precision of the quote asset.
+- `salt`: A unique identifier to create deterministic addresses for deployed oracles.
