+# mDoc Verifier (Testing)
+
+The mDoc Verifier (Testing) is an Android application based on the `appverifier` from the [Google Identity Credential library](https://github.com/openwallet-foundation-labs/identity-credential), implementing ISO/IEC 18013-5:2021.
+
+## Purpose
+
+The mDoc Verifier (Testing) app is provided to help developers test and validate their wallet implementations.
+
+## Modifications
+
+Starting from the original code of the `appverifier` [here](https://github.com/openwallet-foundation-labs/identity-credential/commit/0b9b31ef63047762e10300e23a22f6d7dcfb6d15), the following modifications have been made:
+
+ - Support for requesting EU Documents:
+   - Personal Identification Data (PID) document, according to the ARF PID RuleBook.
+   - Age Verification (Pseudonym) document.
+ - IACA Certificates: Updated to support EUDI Wallet IACAs as trusted certificates.
+ - Reader Authentication Certificate.
+
+The app is available for download from the App Center, [here](https://install.appcenter.ms/orgs/eu-digital-identity-wallet/apps/mdoc-verifier-testing/distribution_groups/eudi%20verifier%20(testing)%20public) 
+(the code is not currently publicly available).
+
+## Important Note
+The mDoc Verifier (Testing) app is a testing tool for developers to validate their wallet implementations. 
+It is not intended for production use. 
+The app may contain bugs or other issues that affect its functionality on different mobile devices or Android versions.
+These issues will be addressed in the upcoming open-source library, which will be available for developers to build their own verifier applications.
