 ## How it works
 
-The Eco Facet works by ...
+The EcoFacet enables cross-chain bridging through the Eco protocol. It allows users to bridge tokens across chains with optional destination chain calls, supporting both immediate execution and deferred proving mechanisms.
 
 ```mermaid

     D{LiFiDiamond}-- DELEGATECALL -->EcoFacet;
-    EcoFacet -- CALL --> C(Eco)
+    EcoFacet -- CALL --> C(Eco Portal)
 ```
 
 ## Public Methods
 
 - `function startBridgeTokensViaEco(BridgeData calldata _bridgeData, EcoData calldata _ecoData)`
-  - Simply bridges tokens using eco
-- `swapAndStartBridgeTokensViaEco(BridgeData memory _bridgeData, LibSwap.SwapData[] calldata _swapData, ecoData memory _ecoData)`
-  - Performs swap(s) before bridging tokens using eco
