+Plugin that sends heartbeat stream event.
+
+Stream events are associated with a project ref for visibility purposes so the heartbeat is no different. The defaut settings will send an event on the refs/meta/config ref of the All-Projects project every 15 seconds.
+
+To configure heartbeat, refer to [config](config.html) documentation.

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

+Heartbeat Configuration
+=========================
+File `heartbeat.config`
+-------------------------
+
+The optional file `$site_path/etc/heartbeat.config` is a Git-style config file that controls the heartbeat settings for the heartbeat plugin.
+
+The file is composed of one `heartbeat` section with the following optional parameters.
+
+delay: time in milliseconds to send heartbeat (defaults to 15000)
+
+project: project on which to send event (default is All-Projets)
+
+ref: ref on which to send event (default is refs/meta/config)
