Hello guys,

I will do a quick guide on how to install Ruby on Rails on a Windows machine.

Things you'll need to download:
Ruby 2.0.x
A development kit, I'll be using one called DevKit-tdm-32-4.5.2-20111229-1559-sfx
RubyGems

When you've downloaded Ruby installer, run it and you should see a window like this:

You don't need to check any of the boxes, leave it as it is.

Extract the DevKit to any folder you want, and remember the folders location.
Now I will asume that you've put into C:\DevKit
The next thing you'll need to do is to search for a program called "Start command prompt with ruby".

Open the command prompt and type a command
Code:
CD C:\DevKit
This will select the folder we'll be loading the kit from.
Go on and type
Code:
ruby dk.rb init
When you see a message
Initialization complete! Please review and modify the auto-generated'config.yml' file to ensure it contains the root directories to all of the installed Rubies you want enhanced by the DevKit.
Enter the next line
Code:
ruby dk.rb install
After a couple of lines you'll see that you've succesfully implemented the Development kit.

Extract your downloaded rubygems into a folder, and go there with CD
Code:
CD C:\Ruby200\RubyGemsx.x.x
Note: x.x.x means your version of RubyGems.
And type
Code:
ruby setup.rb
This will install the gems.

Now go back to the bin folder by writing:

Code:
CD C:\Ruby200\bin
Note: Ruby folder name may vary according to the current version.
And enter a line
Code:
gem install -r rails
Wait for a couple of minutes and when the lines stop, check if you've installed everything correctly by writing:
Code:
ruby -v
and
Code:
rails -v
If you don't get any error messages, congratulations, you've just installed Ruby On Rails.

To be continued...

Peace,
Vincentas
