 A module is a set of packages with a manifest file (`neva.yaml`). When we created our project with `neva new`, it generated a basic module with the following manifest file:
 
 ```yaml
-neva: 0.30.1
+neva: 0.30.2
 ```
 
 This defines the Nevalang version for our project. As your project grows, you can include dependencies on third-party modules here.
