+# Java Native Interface for C++
+
+## Overview
+
+JNIPP is just a C++ wrapper for the standard Java Native Interface (JNI). It
+tries to take some of the long-winded annoyance out of integrating your Java
+and C++ code.
+
+While this project has so far just been a utility library for my own usage,
+it seems to have caught the eye of some others who have also been looking for
+a suitable C++ JNI layer.  If you have feature requests, do not hesitate to
+submit them as Github issues.  Please be descriptive in your feature request.
+The more useful information you provide - along with justification on why it
+should be implemented - the more likely it is that I will add your feature.
+
+## Requirements
+
+To compile you will need:
+
+- A C++11 compatible compiler
+- An installation of the Java Development Kit (JDK)
+- The `JAVA_HOME` environment variable, directed to your JDK installation.
+
+## Usage
+
+> For comprehensive examples on how to use *jnipp*, see the `tests` project
+> in the project source code.
+
+There are two situations where the Java Native Interface would be needed.
+
+- A Java application calling C/C++ functions; or
+- A C/C++ application calling Java methods
+
+### Calling Java from C++
+
+The following is an example of calling Java from C++.
+
+```C++
+#include <jnipp.h>
+
+int main()
+{
+    // An instance of the Java VM needs to be created.
+    jni::Vm vm;
+
+    // Create an instance of java.lang.Integer
+    jni::Class Integer = jni::Class("java/lang/Integer");
+    jni::Object i = Integer.newInstance("1000");
+
+    // Call the `toString` method on that integer
+    std::string str = i.call<std::string>("toString");
+
+    // The Java VM is automatically destroyed when it goes out of scope.
+    return 0;
+}
+```
+
+### Calling C++ from Java
+
+Consider a basic Java program:
+
+```Java
+package com.example;
+
+class Demo {
+    public int value;
+
+    public static void main(String[] args) {
+        Demo demo = new Demo();
+        demo.value = 1000;
+        demo.run();
+    }
+
+    public native void run();
+}
+```
+
+A matching C++ library which uses *jnipp* could look like:
+
+```C++
+#include <jnipp.h>
+#include <iostream>
+
+/*
+    The signature here is defind by the JNI standard, so must be adhered to.
+    Although, to prevent pollution of the global namespace, the JNIEnv and
+    jobject types defind by the standard JNI have been placed into the
+    jni namespace.
+ */
+extern "C" void Java_com_example_Demo_run(jni::JNIEnv* env, jni::jobject obj)
+{
+    // jnipp only needs initialising once, but it doesn't hurt to do it again.
+    jni::init(env);
+
+    // Capture the supplied object.
+    jni::Object demo(obj);
+
+    // Print the contents of the `value` field to stdout.
+    std::cout << demo.get<int>("value") << std::endl;
+}
+```
+
+## Configuration
+
+By default, *jnipp* uses std::runtime_error as the base exception class. If you wish,
+you can define `JNIPP_EXCEPTION_CLASS` to be the exception class you wish to use, before
+including `jnipp.h`. It just needs a `const char*` constructor.
