+# Geode REST API example
+
+This is a simple example that demonstrates putting values into a
+replicated region and retrieving the values using the Geode REST API. For enabling the REST API you can follow the official [document](https://geode.apache.org/docs/guide/19/rest_apps/setup_config.html#setup_config_enabling_rest).
+
+This example assumes you have installed Java and Geode.
+
+## Steps
+
+1. From the `geode-examples/rest` directory, build the example and
+ run unit tests
+
+ $ ../gradlew build
+
+2. Next start the locator and two servers
+
+ $ gfsh run --file=scripts/start.gfsh
+
+3. Run the example to create and get entries using HTTP Java Client from the region
+
+ $ ../gradlew run
+
+4. Shut down the system:
+
+ $ gfsh run --file=scripts/stop.gfsh
