+Build
+=====
+
+This plugin is built with Buck.
+
+Clone or link this plugin and the its-base plugin to the plugins directory
+of Gerrit's source tree, and issue the command:
+
+```
+  buck build plugins/its-bugzilla
+```
+
+The output is created in
+
+```
+  buck-out/gen/plugins/its-bugzilla/its-bugzilla.jar
+```
+
+This project can be imported into the Eclipse IDE:
+
+```
+  ./tools/eclipse/project.py
+```
+
+To execute the tests run:
+
+```
+  buck test --all --include its-bugzilla
+```
+
+Note that for compatibility reasons a Maven build is provided, but is considered
+to be deprecated and will be removed in a future version of this plugin.
+
+To build with Maven, change directory to the plugin folder and issue the
+command:
+
+```
+  mvn clean package
+```
+
+When building with Maven, the Gerrit Plugin API must be available.
+
+How to build the Gerrit Plugin API is described in the [Gerrit
+documentation](../../../Documentation/dev-buck.html#_extension_and_plugin_api_jar_files).
