+Build
+=====
+
+This plugin is built with Buck or Maven.
+
+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 @PLUGIN@ directory:
+
+```
+  cd @PLUGIN@ && ln -s ../bucklets .
+```
+
+Add link to the .buckversion file:
+
+```
+  cd @PLUGIN@ && ln -s bucklets/buckversion .buckversion
+```
+
+Add link to the .watchmanconfig file:
+
+```
+  cd @PLUGIN@ && ln -s bucklets/watchmanconfig .watchmanconfig
+```
+
+To build the plugin, issue the following command:
+
+```
+  buck build plugin
+```
+
+The output is created in:
+
+```
+  buck-out/gen/@PLUGIN@.jar
+```
+
+This project can be imported into the Eclipse IDE:
+
+```
+  ./bucklets/tools/eclipse.py
+```
+
+To execute the tests run:
+
+```
+  buck test
+```
+
+To build plugin sources run:
+
+```
+  buck build src
+```
+
+The output is created in:
+
+```
+  buck-out/gen/@PLUGIN@-sources.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/@PLUGIN@
+```
+
+The output is created in:
+
+```
+  buck-out/gen/plugins/@PLUGIN@/@PLUGIN@.jar
+```
+
+This project can be imported into the Eclipse IDE:
+
+```
+  ./tools/eclipse/project.py
+```
+
+To execute the tests run:
+
+```
+  buck test --include @PLUGIN@
+```
+
+Maven
+-----
+
+To build with Maven, run
+
+```
+mvn clean package
+```
+
+How to build the Gerrit Plugin API is described in the [Gerrit
+documentation](../../../Documentation/dev-buck.html#_extension_and_plugin_api_jar_files).
