 ### Snapshot Tests
 
-If you make changes to the UI you may cause existing UI Snapshot tests to fail. You can run the snapshot tests using `UITests` target. To update the reference snapshots, delete them from `element-x-ios/UITests/Sources/__Snapshots__/Application` and run the tests again. 
-These are the devices we store snapshots for that you will need to run against which need to use the iOS 16.4 simulator in en-US for consistency:
-- iPhone 14
-- iPad (9th generation)

+If you make changes to the UI you may cause existing UI and Preview test snapshots to fail. The UITests run user flows and record snapshots while doing so using the settings defined under [checkEnvironments](https://github.com/element-hq/element-x-ios/blob/c29175d1f924e58b9646a200dbab0301fce3c258/UITests/Sources/Application.swift#L35-L37) while the PreviewTests use the settings defined in [PreviewTests.swift](https://github.com/element-hq/element-x-ios/blob/c29175d1f924e58b9646a200dbab0301fce3c258/PreviewTests/Sources/PreviewTests.swift#L18-L20). The snapshots are stored under `Sources/__Snapshots__` in their respective target's folder.
