Frequently Asked Questions
Two things: whether any pattern line appears more than once (duplicates), and which of 6 common patterns — node_modules/, .env, .DS_Store, dist/, *.log, .env.local — are present or missing, shown as a checklist.
No — the checklist is a small fixed set of generally common patterns, not tailored to any specific language, framework, or IDE. For a comprehensive starting template, use github.com/github/gitignore.
No — it doesn't check whether your patterns are syntactically valid gitignore glob rules, only whether lines are duplicated and whether the 6 common patterns appear.
No — the check runs entirely in your browser.
