# 1. Set up the python-MCS-SDK

To begin using Swan Storage, you need to install and configure the python-MCS-SDK.

### 1.1 Install Python

Ensure you have Python 3.7 or later installed on your system.

For information about how to get the latest version of Python, see the official [Python documentation](https://www.python.org/downloads/).

### 1.2 Install python-MCS-SDK

Install the latest python-MCS-SDK release via **pip:**

`pip install python-MCS-SDK`

{% hint style="info" %}
The latest development version of python-MCS-SDK is on [GitHub](https://github.com/filswan/python-mcs-sdk)
{% endhint %}

### 1.3 Configure the SDK

Before using the SDK, you need to generate an API key from the MCS website.

### 1.4 Initialize the SDK

To use python-MCS-SDK, you must first import it and state your identity.

```python
from swan_mcs import APIClient
import logging
# Set logging level to be sure that you can see the info level message
logging.basicConfig(level=logging.INFO)
# Let's initialize the Python-MCS-SDK
mcs_api = APIClient("<API_KEY>")
```

If you see "Login Successful" in the console, you have logged in successfully. The following code will take you through the initialization of services.

```python
from swan_mcs import BucketAPI
# Init bucket client
bucket_client = BucketAPI(mcs_api)
```
