+This is a convenience plugin that allows users to easily copy the change-ref of a change.
+
+It provides the following Gerrit UI enhancements.
+
+* Adds a ref copy link to the download menu.
+* Adds a copyable ref as a change-metadata-item.
+
+> Note: As this plugin is Polymer 3 compliant,
+it was designed to work for Gerrit v3.3 and newer [1]

+Build
+=====
+
+This @PLUGIN@ plugin is built with Bazel.
+
+Clone (or link) this plugin to the `plugins` directory of Gerrit's source tree.
+
+Then issue
+
+```
+  bazel build plugins/@PLUGIN@
+```
+
+in the root of Gerrit's source tree to build
+
+The output is created in
+
+```
+  bazel-genfiles/plugins/@PLUGIN@/@PLUGIN@.jar
+```
+
+This project can be imported into the Eclipse IDE.
+Add the plugin name to the `CUSTOM_PLUGINS` set in
+Gerrit core in `tools/bzl/plugins.bzl`, and execute:
+
+```
+  ./tools/eclipse/project.py
+```
+
+To execute the tests run:
+
+```
+  bazel test plugins/@PLUGIN@:all
+```
+
+How to build the Gerrit Plugin API is described in the [Gerrit
+documentation](../../../Documentation/dev-bazel.html#_extension_and_plugin_api_jar_files).
