+# Gerrit multi-site plugin
+
+This plugin allows having multiple Gerrit masters to be deployed across various
+sites without having to share any storage. The alignment between the masters
+happens using the replication plugin and an external message broker.
+
+The Gerrit masters requirements are:
+
+- Gerrit v2.16.5 or later
+- Migrated to NoteDb
+- Connected to the same message broker
+- Accessible behind a load balancer (e.g., HAProxy)
+
+Currently, the only mode supported is one primary read/write master
+and multiple read-only masters but eventually the plan is to support N
+read/write masters. The read/write master is handling any traffic while the
+read-only masters are serving the Gerrit GUI assets, the HTTP GET REST API and
+the git-upload-packs. The read-only masters are kept updated to be always ready
+to become a read/write master.
+
+For more details on the overall multi-site design and roadmap, please refer
+to the [multi-site plugin DESIGN.md document](DESIGN.md)
+
+## License
+
+This plugin is released under the same Apache 2.0 license and copyright holders
+as of the Gerrit Code Review project.
+
+## How to build
+
+The multi-site plugin is built like any other Gerrit plugin in tree mode, by cloning
+Gerrit and the multi-site plugin code, and checking them out on the desired branch.
+
+Example of cloning Gerrit and multi-site for a stable-2.16 build:
+
+```
+git clone -b stable-2.16 https://gerrit.googlesource.com/gerrit
+git clone -b stable-2.16 https://gerrit.googlesource.com/plugins/multi-site
+
+cd gerrit/plugins
+ln -s ../../multi-site .
+rm external_plugin_deps.bzl
+ln -s multi-site/external_plugin_deps.bzl .
+```
+
+Example of building the multi-site plugin:
+
+```
+cd gerrit
+bazel build plugins/multi-site
+```
+
+The multi-site.jar plugin is generated to `bazel-genfiles/plugins/multi-site/multi-site.jar`.
+
+Example of testing the multi-site plugin:
+
+```
+cd gerrit
+bazel test plugins/multi-site:multi_site_tests
+```
+
+**NOTE**: The multi-site tests include also the use of Docker containers for
+instantiating and using a Kafka/Zookeeper broker. Make sure you have a Docker
+daemon running (/var/run/docker.sock accessible) or a DOCKER_HOST pointing to
+a Docker server.
+
+## How to configure
+
+Install the multi-site plugin into the `$GERRIT_SITE/plugins` directory of all
+the Gerrit servers that are part of the multi-site cluster.
+
+Create the `$GERRIT_SITE/etc/multi-site.config` on all Gerrit servers with the
+following basic settings:
+
+```
+[kafka]
+ bootstrapServers = <kafka-host>:<kafka-port>
+
+[kafka "publisher"]
+ enabled = true
+
+[kafka "subscriber"]
+ enabled = true
+```
+
+For more details on the configuration settings, please refer to the
+[multi-site configuration documentation](src/main/resources/Documentation/config.md).
+
+You need also to setup the Git-level replication between nodes, for more details
+please refer to the
+[replication plugin documentation](https://gerrit.googlesource.com/plugins/replication/+/refs/heads/master/src/main/resources/Documentation/config.md).
