-To use as a docker action
+
+## Quick Java Action
+A Java action is a Java program with a method called `main` that has the exact signature as follows:
+```java
+public static com.google.gson.JsonObject main(com.google.gson.JsonObject);
+```
+
+For example, create a Java file called `Hello.java` with the following content:
+
+```java
+import com.google.gson.JsonObject;
+
+public class Hello {
+    public static JsonObject main(JsonObject args) {
+        String name = "stranger";
+        if (args.has("name"))
+            name = args.getAsJsonPrimitive("name").getAsString();
+        JsonObject response = new JsonObject();
+        response.addProperty("greeting", "Hello " + name + "!");
+        return response;
+    }
+}
+```
+In order to compile, test and archive Java files, you must have a [JDK 8](http://openjdk.java.net/install/) installed locally.
+
+Then, compile `Hello.java` into a JAR file `hello.jar` as follows:
+```
+javac Hello.java
+```
+```
+jar cvf hello.jar Hello.class
+```
+
+**Note:** [google-gson](https://github.com/google/gson) must exist in your Java CLASSPATH when compiling the Java file.
+
+
+
+When you use the command line and a `.jar` source file, you do not need to
+specify that you are creating a Java action;
+the tool determines that from the file extension.
 
 Review comment:
   Do you mean that `--kind` does not need to be specified?
