+### Increasing the GHOST borrow rates
+To simulate interest rate changes on GHOST you first need to deposit some money into the vault and then borrow as much as possible against it.
+You can do this using the CLI and execute txs manually or you can use the [planfile](../README.md#planfiles) to mock it on deployment.
