 ## Usage
 
 To run the action with the latest swift version available, simply add the action as a step in your workflow:
 
 ```yaml
-- uses: swift-actions/setup-swift@v2
+- uses: swift-actions/setup-swift@v3
 ```
 
 After the environment is configured you can run swift commands using the standard [`run`](https://help.github.com/en/actions/automating-your-workflow-with-github-actions/workflow-syntax-for-github-actions#jobsjob_idstepsrun) step:

-## Note about versions
-
-This project uses strict semantic versioning to determine what version of Swift to configure. This differs slightly from the official convention used by Swift.
-
-For example, Swift is available as version `5.1` but using this as value for `swift-version` will be interpreted as a version _range_ of `5.1.X` where `X` is the latest patch version available for that major and minor version.

-In other words specifying...
+If you are running on a runner that is not able to verify the GPG signature of the Swiftly package, you can skip the verification by setting the `skip-verify-signature` input to `true`.
