+* A directory on a shared file system must be available for @PLUGIN@ to use
+* An implementation of global-refdb (e.g. Zookeeper) must be accessible from all the active

+* Configure gerrit.serverId in gerrit.config based on [config](config.md)'s introduction
+* Install and configure this @PLUGIN@ plugin [further](config.md) or based on example

+* Install @PLUGIN@ plugin as a database module in $GERRIT_SITE/lib(please note that
+@PLUGIN plugin must be installed as a plugin and as a database module) and add

+=====
 
-This plugin can be built with Bazel, and two build modes are supported:
-
-* Standalone
-* In Gerrit tree
-
-Standalone build mode is recommended, as this mode doesn't require local Gerrit
-tree to exist. Moreover, there are some limitations and additional manual steps
-required when building in Gerrit tree mode (see corresponding sections).
-
-## Build standalone
-
-To build the plugin, issue the following command:
-
-```
-  bazel build @PLUGIN@
-```
-
-The output is created in
-
-```
-  bazel-bin/@PLUGIN@.jar
-```
-
-To package the plugin sources run:
-
-```
-  bazel build lib@PLUGIN@__plugin-src.jar
-```
-
-The output is created in:
-
-```
-  bazel-bin/lib@PLUGIN@__plugin-src.jar
-```
-
-To execute the tests run:
-
-```
-  bazel test //...
-```
-
-This project can be imported into the Eclipse IDE:
-
-```
-  ./tools/eclipse/project.sh
-```
-
-## Build in Gerrit tree
+This plugin can be built with Bazel in the Gerrit tree.
