Dear Unni,
It may be worth it to go and read:
http://www.railsdocumentation.org/getting_started_with_rails.pdf
It is a work in progress, but it will help you out with getting started.
Regards
Mikel
These are my notes for installing rails, maybe something in there will help:
Try: C:>**gem install rails --include-dependencies**
``or: C:>** gem install rails -remote ** (answer “y” to all five questions)
If they both fail, download the latest rails.gem file from http://rubyforge.org/frs/?group_id=307
Install the downloaded gem via the command line: C:\My downloads\Ruby
