+
+## Overview
+Groovy interpreter for Apache Zeppelin
+
+## Run the interpreter with docker
+You can run the Groovy interpreter as a standalone docker container.
+
+### Step 1. Specify the configuration for the Groovy interpreter
+```bash
+    # conf/interpreter.json
+
+    "groovy": {
+      ...
+      "option":
+      } {
+        "remote": true,
+        "port": {INTERPRETER_PROCESS_PORT_IN_HOST},
+        "isExistingProcess": true,
+        "host": "localhost",
+        ...
+      }
+````
+
+### Step 2. Build and run the Groovy interpreter
+```bash
+$ ./mvnw clean install -DskipTests
+
+$ ./bin/zeppelin-daemon.sh start # start zeppelin server.
+# check the port of the interpreter event server. you can find it by looking for the log that starts with "InterpreterEventServer is starting at"
+
+$ docker build -f ./groovy/Dockerfile -t groovy-interpreter .
+
+$ docker run -p {INTERPRETER_PROCESS_PORT_IN_HOST}:8180 \
+  -e INTERPRETER_EVENT_SERVER_PORT={INTERPRETER_EVENT_SERVER_PORT} \
+  groovy-interpreter
+```
