+# Jakarta Mail
+
+[![Build Status](https://github.com/eclipse-ee4j/mail/actions/workflows/maven.yml/badge.svg?branch=master)](https://github.com/eclipse-ee4j/mail/actions/workflows/maven.yml?branch=master)
+[![Jakarta Staging (Snapshots)](https://img.shields.io/nexus/s/https/jakarta.oss.sonatype.org/jakarta.mail/jakarta.mail-api.svg)](https://jakarta.oss.sonatype.org/content/repositories/staging/jakarta/mail/jakarta.mail-api/)
+
+Jakarta Mail defines a platform-independent and protocol-independent
+framework to build mail and messaging applications.
+
+**IMPORTANT:** Implementation of the Jakarta Mail API, aka JakartaMail (formerly JavaMail),
+is no longer part of this repository.
+As part of breaking tight integration between Jakarta Mail API and the implementation,
+its sources were moved to the new project - [Eclipse Angus](https://github.com/eclipse-ee4j/angus-mail) -
+and further development continues there. [Eclipse Angus](https://github.com/eclipse-ee4j/angus-mail) 
+is direct accessor of JavaMail/JakartaMail.
+
