What would you recommend as the best free online resource / tutorial to learn Agile Software Development methods?

I'm trying to learn Agile Software Development principles in a hurry and don't have time to wait for a book to arrive.

What would you recommend as the best free online tutorial on Agile Development methodology?

Edit: I agree with the answers that learning things in a hurry is not the way to go about it but as one poster guessed, I'm trying to get an overview of the topic for an interview.

• http://en.wikipedia.org/wiki/Agile_software_development

  From Bob Dizzle

• XP and scrum are decent places to start.

  From David Smart

• Jim Shore's Blog: http://jamesshore.com/Blog/

  But after reading it you will want to buy his book: http://jamesshore.com/Agile-Book/

  From Chris Bilson

• I think you have bigger problems then needing to learn agile development, generally learning something vital in a short amount of time is going to cause you more problems then it is worth. You should take the time and LEARN it good.

  Bob Dizzle : yeah learn it good

• I know this isn't going to be what you want, but...

  I am personally of the opinion that you can't really learn good software development principles until you see bad ideas crash and burn. I spent a year as the lead developer on a project that...shall we say, could have been better-managed. I learned a LOT from it, both about my own practices and about what generally does and doesn't going to work.

• I assume you are looking for an overview for a job interview or something rather than actually trying to bring a development group up to speed in a few days.

  You might check C2, IIRC they were the ones that originated a lot of the agile stuff--the first agile wiki (the first wiki possibly), they are still up and still maintained.

  Good luck

• I've found Steve McConnell's Construx Software website to be a great resource, with lots of agile information. It's a fun place to spend some time browsing white papers.

  From Jason Gallaugher

• I would heartily recommend reading Scrum and XP from the trenches. Its very hands on and gives good pointers on how to start implementing scrum in the organization and outlines both methodologies and tools in an easy to read way.

  Its a 140 page document, but it takes just a few hours to read.
