## 🎛 Installation

We offer three convenient ways to install the 🐍 snekmate contracts:

### 1️⃣ Foundry

You can install 🐍 snekmate via submodules using [Foundry](https://github.com/foundry-rs/foundry) with:

```bash
forge install pcaversaccio/snekmate
```

### 2️⃣ PyPI

You can install 🐍 snekmate from [PyPI](https://pypi.org/project/snekmate) with:

```bash
pip install snekmate
```

> You can use `pip install snekmate -t .` to install the contracts directly into the current working directory!

### 3️⃣ npm

You can install 🐍 snekmate from [npm](https://www.npmjs.com/package/snekmate) with:

```bash
npm install --save-dev snekmate
```

Or if you are using [Yarn](https://classic.yarnpkg.com):

```bash
yarn add --dev snekmate
```

## 👩🏼‍⚖️ Tests

This repository contains [Foundry](https://github.com/foundry-rs/foundry)-based unit tests, property-based tests (i.e. fuzzing), and invariant tests for all contracts, if applicable. All tests are run as part of the CI pipeline [`test-contracts`](./.github/workflows/test-contracts.yml).

> **Note:** An _invariant_ is a property of a program that should always hold true. Fuzzing is a way of checking whether the invariant is falsifiable.
