# Prerequisites and setup

> Installing the adaptive_harmony python library

The only prerequisite to start writing custom recipes is to install `adaptive_harmony`, which is publicly hosted on [Pypi](https://pypi.org/).

```bash theme={null}
pip install adaptive-harmony
```

This library allows you to get a [direct connection](/v0.14/harmony/harmony-client) from your local environment to your Adaptive Engine deployment's compute plane, enabling you to write recipes in your local environment and execute them remotely line-by-line seamlessly.
