 This package contains various contracts which allow you to streamline testing within the aave protocol in foundry.
 
-## GovHelpers
+## GovHelpers (deprecated)
 
 These helpers allow you to create and execute proposals on L1 so you don't have to care about having enough proposition power, timings, etc.
 
+## GovV3Helpers
+
+These helpers allow the creation of proposal for aave governance v3.
+
+The GovernanceV3Helpers also contain scripts to cast a vote directly via foundry.
+To do so just run `make vote proposalId=n support=true/false`.
+
 ## ProxyHelpers
 
 These helpers allow you to fetch the current implementation & admin for a specified proxy.

 The ProtocolV3TestBase is intended to be used with proposals that alter a V3 pool. While the `helpers` are libraries, you can use from where ever you want `ProtocolV3TestBase` is intended to be inherited from in your test via `is ProtocolV3TestBase`.
 
 When inheriting from `ProtocolV3TestBase` you have access to methods to create readable configuration snapshots of a pool and e2e tests of a pool.

+## ProtocolV2TestBase
+
+Analog to ProtocolV3TestBase but for v2 pools.
