Hit the obvious stuff (speeds, altitudes, "don't turn before", equipment requirements). Remember this chart references other charts. So if you're exempt from RNP-1 it'll reference another chart. I think there are some transition routes that reference a chart after that. I think there's another chart specific for times, too. So one chart references a bunch of other charts. Overseas it's pretty common for jepp-charts to cross reference each other quite a bit, and the way they do so varies from place to place. You have several hours in cruise to peruse the details.
