This section contains a roadmap for the new user with pointers on what to read first.

If you are new to RTI Connext, we recommend starting in the following order:

See the Getting Started Guide. This document provides download and installation instructions. It also lays out the core value and concepts behind the product and takes you step-by-step through the creation of a simple example application.
The User's Manual describes the features of the product and how to use them. It is organized around the structure of the DDS APIs and certain common high-level tasks.
If you are a .NET user, you may want to read the .Net Language Support section of this online documentation before moving on to the programming interfaces themselves. .Net is language-neutral; this section explains how to use the APIs described here from various .Net-compatible languages.
The documentation in the RTI Connext DDS API Reference provides an overview of API classes and modules for the DDS data-centric publish-subscribe (DCPS) package from a programmer's perspective. Start by reading the documentation on the main page.
After reading the high level module documentation, look at the Publication Example and Subscription Example for step-by-step examples of creating a publication and subscription. These are hyperlinked code snippets to the full API documentation, and provide a good place to begin learning the APIs.
Next, work through your own application using the example code files generated by rtiddsgen.
To integrate similar code into your own application and build system, you will likely need to refer to the Platform Notes.
