Installation

Download the Robot IDE jar file and copy it to your Eclipse's plugin directory. You can find the plugin directory under your Eclipse installation directory, eg. ~/eclipse/plugins

Restart your Eclipse and you can now open files with Robot IDE.

Uninstalling

Close your Eclipse and go to your Eclipse plugin directory, usually something like ~/eclipse/plugins and delete or move the Robot IDE plugin file. The plugin name is in the following format

com.nitorcreations.robotframework.eclipseide_<version>.SNAPSHOT.jar

or

com.nitorcreations.robotframework.eclipseide_<version>.jar

depending whether you have installed a stable version or a development version of the plugin. Restart your Eclipse and Robot IDE has been uninstalled.
