The documentation for Fastify is split into two categories:

- [Reference documentation](/docs/latest/Reference/)
- [Guides](/docs/latest/Guides/)

The reference documentation utilizes a very formal style in an effort to document
Fastify's API and implementation details thoroughly for the developer who needs
such. The guides category utilizes an informal educational style as a means to
introduce newcomers to core and advanced Fastify concepts.

## Where To Start

Complete newcomers to Fastify should first read our [Getting
Started](/docs/latest/Guides/Getting-Started/) guide.

Developers experienced with Fastify should consult the [reference
documentation](/docs/latest/Reference/) directly to find the topic they are seeking
more information about.
