## What it is
A Retrofit 2 Converter.Factory that lets Retrofit use kotlinx.serialization for serializing request bodies and deserializing response bodies. It has been deprecated because the converter was merged into Retrofit itself as a first-party converter.

## Use cases
- use kotlinx.serialization with retrofit for  apis
- deserialize retrofit responses into kotlin data classes
- serialize request bodies with kotlinx serialization
- replace gson or moshi with kotlinx.serialization in retrofit
- add a  converter factory to a retrofit builder

## When to choose
- you are stuck on an older Retrofit version that lacks a built-in kotlinx.serialization converter
- you need a stable 1.0.0 converter for a legacy project already using this artifact

## When to avoid
- starting a new project - use the first-party converter in Retrofit itself
- you need updates or bug fixes, since this repo is deprecated and unmaintained
- you use a serialization format other than
