## Installation

Requirements and caveats from upstream:
- <span><img src="https://img.shields.io/docker/pulls/supertokens/supertokens-postgresql.svg" alt="Docker pull stats"/></span>
- for popular languages and front-end frameworks e.g. Node.js, Go, Python, React.js, React Native, Vanilla JS, etc.
- ✅ Whilst running Java can seem difficult, we provide the JDK along with the binary/docker image when distributing it.

Basic usage or getting-started notes:

- We also plan on using [GraalVM](https://www.graalvm.org/) in the future and this can reduce memory usage by 95%!
