In this chapter, we looked at the 30,000-foot view of Ajax and Rails. First with Ajaxits basic mechanisms, motivation, and location in the larger historical context of the Web. We deconstructed the strict acronym interpretation of Ajax and replaced it with a definition centered more on solving problems.
Then we shifted attention to Rails, Ruby, and frameworks in general. We discussed the ideals that guide the development of Rails and the history of Ajax in Rails. In the last section, we fired up the terminal and walked through installing Ruby and Rails, and making sure the whole thing works by creating an application skeleton.
In the next chapter, we'll pick up exactly where we left off and start adding code to the skeleton application.
