-Notes:
-
-- “Manual excludes” means the tool supports flags to ignore paths but doesn’t automatically read .gitignore or provide built-in caching like CodeState.
-- See Performance benchmarks below for speed guidance and how to reproduce measurements.

 ## Why CodeState?
 
 - Instant understanding: go beyond LOC to highlight duplicates, complexity hotspots, refactor candidates, naming issues, and dead code — right in your terminal.

 ## Troubleshooting
 
-- Command not found: try `python -m codestate.cli` instead of `codestate`.
 - Windows path/encoding quirks: run from a local folder (avoid syncing folders) and ensure UTF-8 console.
 - Very large repos: run once with `--cache`, then subsequent commands will be much faster.
