Spanish pronunciation and grammar

It would be really complicated to post articles about the Spanish grammar besides the word learning articles, so I simply show this book and you can learn from it anytime you want. :)

In my opinion this is a great starting book(and also free). I like it because I can easily understand it, learn from it really quickly, lots of useful sentences and words, all of the major grammar rules are in it.
