- [Enrichment with clinical context](https://imo.ferndocs.com/documentation/guides/enrichment.md): Problem-domain matching that weighs the patient, not just the string.
- [Sessions and feedback](https://imo.ferndocs.com/documentation/guides/sessions-and-feedback.md): Correlate normalization activity with what your users actually chose.
- [Code systems and mappings](https://imo.ferndocs.com/documentation/guides/code-systems.md): What every matched lexical carries with it.
- [Errors and rate limits](https://imo.ferndocs.com/documentation/guides/errors-and-limits.md): The error envelope, what each status means, and how to retry correctly.
