== Overview ==

Here we download and install the latest version of ''Eclipse'' onto your machine. ''Eclipse'' is a popular IDE for Java developers. (IDEs are software tools that help you edit your source code and compile your projects.)

== Process ==

=== 1. Download Eclipse ===

Go to [[http://www.eclipse.org/downloads/]].

Select ''Eclipse IDE for Java Developers''. (There are several distributions of Eclipse available on the Download page. At a minimum Cytoscape development requires support for Java development and Maven, both of which are available in this distribution.)

On the top-right under ''Download Links'', choose your computer's platform.

{i} ~-''32 or 64-bit?'' We strongly encourage you to use the '''64-bit version''' of Eclipse.-~
