STAR is a nice all around fund with 60/40 stocks and bonds, plus large, small, and international stocks. That is good diversification between several investment classes. It is one of the few funds that require less than $3k to open it, so that is probably why Vanguard put you there. A 60/40 split may be conservative, depending on your age. You may also consider a target date fund until you learn enough about investing to decide what asset allocation you want. Target funds automatically adjust their mix to be age appropriate for some theoretical average investor.
