 - A `/usr/local/bin/tampio` wrapper makes it callable as a plain command
 - Goal: `docker compose run --rm tampio` gives a working shell with no manual setup
 
-## Open Questions
-
-- [ ] Docs language: bilingual FI/EN or English only? (bilingual fits the theme)
-- [ ] Scope: curated examples repo, or also a GitHub Pages web showcase / playground?
-- [ ] Hosting: GitHub (likely — standard for open source)
-- [ ] Is Tampio working locally? The libvoikko dependency can be tricky; Docker is the primary path until confirmed.

 ## Notes
 
 - Project name: **Tampiorama**
-- libvoikko local setup not yet confirmed working — Docker is the primary path
-- `docs/cheatsheet.md` should cover annotated grammar constructs (Finnish cases → parameter roles) as well as raw syntax
