I mention all this stuff because the file looks truncated. The main reasons it looks truncated are that (1) there's no title page, (2) the first item in the table of contents is all lower case and indented, and (3) generally the first page or so is a jump-start, and not hierarchically organized. If you just ignore these confusing elements, there's a lot of useful information here. The tutorial doesn't seem to be missing some initial bit.
