 If you're using Slate for the first time, check out the [Getting Started](./docs/getting-started) guide and the [Core Concepts](./docs/concepts) to familiarize yourself with Slate's architecture and mental models. Once you've gotten familiar with those, you'll probably want to check out the full [API Reference](./docs/reference).
