Read an intro paragraph on pronouns, (the book will cover it more later in the chapter I'm on). It was very brief, then went into adjectives, it basically gave 4 examples using the adjectives schön, weiß, klein, and groß. It mentioned how the spelling can change depending if a noun is singular/plural, or what if any article is infront of it. But it didn't really explain much more, it just gave some examples with using both definite and indefinite articles and on example had no article at all.

I skimmed through a little bit more of the chapter before I actually go and write down any notes in my notebook, and it looks like it goes a little more into detail about "einen" and "einem". Then kind of shows you the different forms of "you", I can't remember. Everything in that book so far is just really brief explanations of things with examples of how the words are used, it meant for beginners.
