Skip is a LINQ sequence operation that omits a specified number of elements from the beginning of a sequence. In a paged board-game API, pageIndex multiplied by pageSize determines how many records to omit before returning the requested page. section 5.4.1
The paging query uses Skip(pageIndex * pageSize) followed by Take(pageSize). With zero-based pageIndex values, the first page skips zero records; default values of 0 and 10 provide a usable first page when clients omit parameters. section 5.4.1
