-# UID2Prebid for UDI2 iOS SDK
-
-This project exists because the Prebid mobile SDK for iOS, a dependency for UID2Prebid, does not support Swift Package Manager. It configures the UID2Prebid framework for testing, and houses sources for CocoaPods. If/when Prebid supports SPM, this project will not be necessary.
-
-To bootstrap this project you will need to:
-
-```sh
-cd UID2Prebid
-./bootstrap.sh
-```
-
-To develop & test UID2Prebid, open `UID2Prebid.xcworkspace`.
