- Questions about using the packages: open an issue with the question form. Polish or English is fine.
- Missing or unexpected data: check NBP's API first. The library returns what NBP publishes; the OpenUrzednik.Nbp README lists when NBP publishes and what the API limits are.
- Bugs and feature requests: use the other issue forms.
- Security vulnerabilities: never in a public issue. See SECURITY.md.
- Code of conduct concerns: see CODE_OF_CONDUCT.md.
