# Levelica

> Levelica turns any skill into a 7-level sequence so you can see where you stand and what to work on next. Each Level Guide breaks one skill — from chess to public speaking to backend engineering — into Lv.1 through Lv.7 with observable checklists grounded in published frameworks and research. All guides are available in English and Korean.

## Level Guide structure

- Every guide has exactly 7 levels. Lv.1 is first entry into the domain; Lv.7 is contribution that shapes the field for others.
- Each level has a summary, a description, and a checklist of at least 5 observable criteria. Checking at least 80% of a level’s items achieves it, and your level is the highest one achieved.
- Each guide cites the sources behind its level boundaries and checklist items (rating systems, competency frameworks, certifications, academic research) in a References section.
- Every guide page has a markdown version: append `.md` to its URL, e.g. https://www.levelica.com/en/guides/chess.md (Korean: https://www.levelica.com/ko/guides/chess.md).
