I've just started this book and already the author has given several instructions on what to do, assuming the reader knows how. For such a long book you'd think there would be more instructions, but you'd be surprised by how many times just in the first few chapters you're told to do something with very loose instructions on HOW.

FYI, if I'm reading a book with BEGINNERS in the title, maybe you should tell me HOW to setup the MySql database, don't just give me what you typed into your command shell on a "Unix variant" machine. That does me no good.

我刚刚开始写这本书，作者已经给出了一些关于如何做的说明，假设读者知道怎么做。对于这么长的一本书，你可能会认为会有更多的说明，但你会惊讶地发现，就在前几章，有多少次你被告知要做一些事情，但说明却非常松散。
仅供参考，如果我正在读一本书，书名是初学者，也许你应该告诉我如何设置MySql数据库，不要只告诉我你在“Unix variant”机器上输入命令shell的内容。那对我没有好处。
