## Quick Links:

* Learn how t**o create a simple Pronghorn app** by following the [**Hello World Example**](https://oci-pronghorn.gitbook.io/pronghorn/chapter-0-what-is-pronghorn/home). You can also use the chapters on the left as a reference for building better Pronghorn applications.
* Visit the [**Downloads**](https://oci-pronghorn.gitbook.io/pronghorn/chapter-0-what-is-pronghorn/downloads) page for more information on how to download using Maven and other methods.

## What is Pronghorn?

> The **actor model** in [computer science](https://en.wikipedia.org/wiki/Computer_science) is a [mathematical model](https://en.wikipedia.org/wiki/Mathematical_model) of [concurrent computation](https://en.wikipedia.org/wiki/Concurrent_computation) that treats "actors" as the universal primitives of concurrent computation. In response to a [message](https://en.wikipedia.org/wiki/Message_\(computing\)) that it receives, an actor can: make local decisions, create more actors, send more messages, and determine how to respond to the next message received. 

Pronghorn is a pragmatic approach to an **actor based framework**. It is a staged event driven single machine embedded micro-framework written in Java, designed to be garbage-free with a small memory footprint.

## JavaDocs

The JavaDoc for every major Pronghorn-related project is listed below:

## Examples

### GreenLightning

For a project built completely with Pronghorn, there is GreenLighting, an incredibly fast & lightweight microservices framework.

### JPG-Raster

For a real-world example of Pronghorn, please see [JPG-Raster](https://oci-pronghorn.gitbook.io/pronghorn/chapter-6-example-projects/jpg-raster), a fast JPG encoder/decoder:

### Web Cookbook

Another example is the [Web Cookbook](https://oci-pronghorn.gitbook.io/pronghorn/chapter-6-example-projects/web-cookbook). It demonstrates how to build a HTTP server, proxy, and more:
