# Reference

Look up a field, setting, or term while you work. If you are new to Flashnerd, start with [your first study session](https://docs.flashnerd.com/guide/getting-started/getting-started.md).

## Card fields

The [field reference](https://docs.flashnerd.com/reference/fields/index.md) covers all 11 field types, from plain text and audio to cloze, image occlusion, language annotations, code, and TeX. Each field guide explains what to enter, how it appears during study, and which settings affect it.

## Spaced repetition

Start with [creating an SRS set](https://docs.flashnerd.com/guide/srs/getting-started.md), then use these references to understand scheduling and workload:
