+Build
+=====
+
+This plugin can be built with Buck or Maven.
+
+Buck
+----
+
+Two build modes are supported: Standalone and in Gerrit tree.
+The standalone build mode is recommended, as this mode doesn't require
+the Gerrit tree to exist locally.
+
+
+### Build standalone
+
+Clone bucklets library:
+
+```
+  git clone https://gerrit.googlesource.com/bucklets
+
+```
+and link it to quota plugin directory:
+
+```
+  cd quota && ln -s ../bucklets .
+```
+
+Add link to the .buckversion file:
+
+```
+  cd quota && ln -s bucklets/buckversion .buckversion
+```
+
+To build the plugin, issue the following command:
+
+
+```
+  buck build plugin
+```
+
+The output is created in
+
+```
+  buck-out/gen/wip.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/wip
+```
+
+The output is created in
+
+```
+  buck-out/gen/plugins/wip/wip.jar
+```
+
+This project can be imported into the Eclipse IDE:
+
+```
+  ./tools/eclipse/project.py
+```
+
+Maven
+-----
+
+Note that the Maven build is provided for compatibility reasons, but
+it is considered to be deprecated and will be removed in a future
+version of this plugin.
+
+To build with Maven, run
+
+```
+mvn clean package
+```
