Installing Raakt is easy. First, make sure you have Ruby installed. Raakt is distributed as a Ruby gem.
To install the raakt gem in Microsoft Windows, open a command window and type:
gem install raakt
To install the raakt gem in Mac OS X or Linux type:
sudo gem install raakt
The latest version of the Raakt gem will be downloaded. Please note that Raakt depends on Hpricot which will be installed too.
From here you may want to try calling Raakt from the command line with a simple script to test remote websites.
If you want to use Raakt from JRuby you will need to install a special version of Hpricot before installing Raakt. See the the setup instructions for using Raakt in HTMLUnit for more details.
