+Build
+=====
+
+This plugin is built with Buck.
+
+Two build modes are supported: Standalone and in Gerrit tree. Standalone
+build mode is recommended, as this mode doesn't require local Gerrit
+tree to exist.
+
+Build standalone
+----------------
+
+Clone bucklets library:
+
+```
+ git clone https://gerrit.googlesource.com/bucklets
+
+```
+and link it to rabbitmq directory:
+
+```
+ cd rabbitmq && ln -s ../bucklets .
+```
+
+Add link to the .buckversion file:
+
+```
+ cd rabbitmq && ln -s bucklets/buckversion .buckversion
+```
+
+Add link to the .watchmanconfig file:
+
+```
+ cd rabbitmq && ln -s bucklets/watchmanconfig .watchmanconfig
+```
+
+To build the plugin, issue the following command:
+
+
+```
+ buck build plugin
+```
+
+The output is created in
+
+```
+ buck-out/gen/rabbitmq.jar
+```
+
+Build in Gerrit tree
+--------------------
+
+Clone or link this plugin to the plugins directory of Gerrit's source
+tree, and issue the command:
+
+```
+ buck build plugins/rabbitmq
+```
+
+The output is created in
+
+```
+ buck-out/gen/plugins/rabbitmq/rabbitmq.jar
+```
+
+This project can be imported into the Eclipse IDE:
+
+```
+ ./tools/eclipse/project.py
+```
+
+How to build the Gerrit Plugin API is described in the [Gerrit
+documentation](../../../Documentation/dev-buck.html#_extension_and_plugin_api_jar_files).
