One page per survey design, each with the same steps: design, data, effort, rates, totals, results as data, and a plot.
How-to: Tasks
One page per task that cuts across survey designs: catch and harvest from interviews, incomplete trips, progressive counts, sections, season and monthly totals, mark-recapture, interview summaries, scheduling, planning, and plots.

Explanation
Why the estimates are built the way they are: effort and its two-stage variance, catch rates and totals, the variance methods, how an estimator is chosen, where units come from, and when the package refuses.
Reference
Look-up material: the terms the package uses, the bus-route equations, how each estimate maps onto survey package calls, and the conventions every function follows.
