-## 🛟 Friendly by design
-
-- **No cryptic tracebacks**; Hand a function a text column where numbers are needed and you get a clear PercentifyWarning, not an Arrow/NumPy stack trace.
-- **Sensible defaults**; Results come back sorted worst-first, and PCA is standardized out of the box.
-- **DataFrames everywhere**; so the output drops straight into your notebook, your next filter, or your model.
-- **Pandas or polars**; pass either a pandas or polars object and you get the same kind back, no flag needed.

-## 🤝 Contributing
-
-Contributions are welcome but they must follow the repo's guiding principle:
-> Keep each method as direct-to-output as possible. A percentify function should return the single most common answer in one line, and point users to the underlying library (pandas, scipy, statsmodels, scikit-learn) for the full, configurable version when the simplest output isn't what they're after.
-
-**It must support polars.** Every function accepts both pandas and polars objects (via the `@_backend_aware` decorator) and returns the same kind, so any new contribution must keep that parity.
-
-If your idea keeps things that simple and direct:
-- Open an issue first to discuss it
-- Fork the repo
-- Create a branch
-- Commit your changes
-- Open a pull request
