On page 9, it requests the player to choose some background skills, then lists a number of them as Admin 0, Animals 0, etc. Having read farther into the rules, I get that having a "0" skill means that you can actually use that skill with no DM penalty, but that's not really clear to a new reader who has just reached this point. Maybe there should be some kind of quick explanation here?
Here's my attempt at a re-write for clarity:
Skills
Skills are the most important aspect of a Traveller. A Traveller's proficiecty in any skill is denoted by his level in that skill. A Traveller trained in a particular skill will start at skill level 0, meaning you can attempt that skill without penalty. Further details on skills and how to use them are discussed on page 56.
