# Getting Started

## Install

You can install Trellis with any of the following methods:

### Pip

```
pip install trellis_dag
```

### Poetry

```
poetry add trellis_dag
```

### Conda

```
conda install trellis_dag
```

**TODO: This will probably need to change since we're using poetry.**

## Set environment variables

If you’re using our built-in LLM tool, you’ll need to set the OPENAI\_API\_KEY environment variable; either in a .env file or with the following command:

```
export OPENAI_API_KEY=your_key_here
```
