+<p>This document discusses the steps needed for setting up a development environment for creating applications that run on the Apache Apex platform.</p>
+<h2 id="development-tools">Development Tools</h2>
+<p>There are a few tools that will be helpful when developing Apache Apex applications, including:</p>
+<ol>
+<li>
+<p><strong>git</strong> - A revision control system (version 1.7.1 or later). There are multiple git clients available for Windows (<a href="http://git-scm.com/download/win">http://git-scm.com/download/win</a> for example), so download and install a client of your choice.</p>
+</li>
+<li>
+<p><strong>java JDK</strong> (not JRE) - Includes the Java Runtime Environment as well as the Java compiler and a variety of tools (version 1.7.0_79 or later). Can be downloaded from the Oracle website.</p>
+</li>
+<li>
+<p><strong>maven</strong> - Apache Maven is a build system for Java projects (version 3.0.5 or later). It can be downloaded from <a href="https://maven.apache.org/download.cgi">https://maven.apache.org/download.cgi</a>.</p>
+</li>
+<li>
+<p><strong>IDE</strong> (Optional) - If you prefer to use an IDE (Integrated Development Environment) such as <em>NetBeans</em>, <em>Eclipse</em> or <em>IntelliJ</em>, install that as well.</p>
+</li>
+</ol>
+<p>After installing these tools, make sure that the directories containing the executable files are in your PATH environment variable.</p>
+<ul>
+<li><strong>Windows</strong> - Open a console window and enter the command <code>echo %PATH%</code> to see the value of the <code>PATH</code> variable and verify that the above directories for Java, git, and maven executables are present.  JDK executables like <em>java</em> and <em>javac</em>, the directory might be something like <code>C:\\Program Files\\Java\\jdk1.7.0\_80\\bin</code>; for <em>git</em> it might be <code>C:\\Program Files\\Git\\bin</code>; and for maven it might be <code>C:\\Users\\user\\Software\\apache-maven-3.3.3\\bin</code>.  If not, you can change its value clicking on the button at <em>Control Panel</em> &#x21e8; <em>Advanced System Settings</em> &#x21e8; <em>Advanced tab</em> &#x21e8; <em>Environment Variables</em>.</li>
+<li><strong>Linux and Mac</strong> - Open a console/terminal window and enter the command <code>echo $PATH</code> to see the value of the <code>PATH</code> variable and verify that the above directories for Java, git, and maven executables are present.  If not, make sure software is downloaded and installed, and optionally PATH reference is added and exported  in a <code>~/.profile</code> or <code>~/.bash_profile</code>.  For example to add maven located in <code>/sfw/maven/apache-maven-3.3.3</code> to PATH add the line: <code>export PATH=$PATH:/sfw/maven/apache-maven-3.3.3/bin</code></li>
+</ul>

+<h2 id="creating-new-apex-project">Creating New Apex Project</h2>
+<p>After development tools are configured, you can now use the maven archetype to create a basic Apache Apex project.  <strong>Note:</strong> When executing the commands below, replace <code>3.3.0-incubating</code> by <a href="http://apex.apache.org/downloads.html">latest available version</a> of Apache Apex.</p>
+<ul>
+<li>
+<p><strong>Windows</strong> - Create a new Windows command file called <code>newapp.cmd</code> by copying the lines below, and execute it.  When you run this file, the properties will be displayed and you will be prompted with <code>Y: :</code>; just press <strong>Enter</strong> to complete the project generation.  The caret (^) at the end of some lines indicates that a continuation line follows. </p>
+<pre><code>@echo off
+@rem Script for creating a new application
+setlocal
+mvn archetype:generate ^
+ -DarchetypeGroupId=org.apache.apex ^
+ -DarchetypeArtifactId=apex-app-archetype -DarchetypeVersion=3.3.0-incubating ^
+ -DgroupId=com.example -Dpackage=com.example.myapexapp -DartifactId=myapexapp ^
+ -Dversion=1.0-SNAPSHOT
+endlocal
+</code></pre>
+</li>
+<li>
+<p><strong>Linux</strong> - Execute the lines below in a terminal window.  New project will be created in the curent working directory.  The backslash (\) at the end of the lines indicates continuation.</p>
+<pre><code>mvn archetype:generate \
+ -DarchetypeGroupId=org.apache.apex \
+ -DarchetypeArtifactId=apex-app-archetype -DarchetypeVersion=3.2.0-incubating \
+ -DgroupId=com.example -Dpackage=com.example.myapexapp -DartifactId=myapexapp \
+ -Dversion=1.0-SNAPSHOT
+</code></pre>
+</li>
+</ul>
+<p>When the run completes successfully, you should see a new directory named <code>myapexapp</code> containing a maven project for building a basic Apache Apex application. It includes 3 source files:<strong>Application.java</strong>,  <strong>RandomNumberGenerator.java</strong> and <strong>ApplicationTest.java</strong>. You can now build the application by stepping into the new directory and running the maven package command:</p>
+<pre><code>cd myapexapp
+mvn clean package -DskipTests
+</code></pre>
+<p>The build should create the application package file <code>myapexapp/target/myapexapp-1.0-SNAPSHOT.apa</code>. This application package can then be used to launch example application via <strong>dtCli</strong>, or other visual management tools.  When running, this application will generate a stream of random numbers and print them out, each prefixed by the string <code>hello world:</code>.</p>
+<h2 id="building-apex-demos">Building Apex Demos</h2>
+<p>If you want to see more substantial Apex demo applications and the associated source code, you can follow these simple steps to check out and build them.</p>
+<ol>
+<li>
+<p>Check out the source code repositories:</p>
+<pre><code>git clone https://github.com/apache/incubator-apex-core
+git clone https://github.com/apache/incubator-apex-malhar
+</code></pre>
+</li>
+<li>
+<p>Switch to the appropriate release branch and build each repository:</p>
+<pre><code>cd incubator-apex-core
+mvn clean install -DskipTests
+
+cd incubator-apex-malhar
+mvn clean install -DskipTests
+</code></pre>
+</li>
+</ol>
+<p>The <code>install</code> argument to the <code>mvn</code> command installs resources from each project to your local maven repository (typically <code>.m2/repository</code> under your home directory), and <strong>not</strong> to the system directories, so Administrator privileges are not required. The  <code>-DskipTests</code> argument skips running unit tests since they take a long time. If this is a first-time installation, it might take several minutes to complete because maven will download a number of associated plugins.</p>
+<p>After the build completes, you should see the demo application package files in the target directory under each demo subdirectory in <code>incubator-apex-malhar/demos</code>.</p>
+<h2 id="sandbox">Sandbox</h2>
+<p>To jump start development with an Apache Hadoop single node cluster, <a href="https://www.datatorrent.com/download">DataTorrent Sandbox</a> powered by VirtualBox is available on Windows, Linux, or Mac platforms.  The sandbox is configured by default to run with 6GB RAM; if your development machine has 16GB or more, you can increase the sandbox RAM to 8GB or more using the VirtualBox console.  This will yield better performance and support larger applications.  The advantage of developing in the sandbox is that most of the tools (e.g. <em>jdk</em>, <em>git</em>, <em>maven</em>), Hadoop YARN and HDFS, and a distribution of Apache Apex and DataTorrent RTS are pre-installed.  The disadvantage is that the sandbox is a memory-limited environment, and requires settings changes and restarts to adjust memory available for development and testing.</p>
