Every wiki page declares a tier near the top, like **Tier:** [Beginner](Tier-Legend). The tier tells you what the page assumes about your prior qsv experience.

Assumes: Nothing. You can read this page top-to-bottom with no prior qsv knowledge.

Topics include: Installation, basic commands, the cookbook recipes that solve common problems, the FAQ, troubleshooting, and the comparison guide.

Start here if you're new: Installation → Getting Started → Cookbook.

Assumes: You've completed Getting Started and can read the output of qsv <command> --help.

Topics include: Transformations, aggregations, joins, validation, format conversions, HTTP fetching, geospatial commands, AI/documentation commands, and ecosystem integrations.

Assumes: Fluency with qsv. You're comfortable composing pipelines, you know what an index does, and you want to push qsv hard.

Topics include: Polars SQL (sqlp), the Luau and Python DSLs, performance tuning, environment variables, stats and frequency caches, lookup tables, and wiki authoring.
