<a id="introduction"></a>
## Introduction
Integrate eSignatures into your application in minutes. The secure and award-winning Docusign eSignature API makes requesting signatures, automating forms, and tracking documents directly from your app easy.

<a id="installation"></a>
## Installation
This client SDK is provided as open source, which enables you to customize its functionality to suit your particular use case. To do so, download or clone the repository. If the SDK’s given functionality meets your integration needs, or if you’re working through our [code examples](https://developers.docusign.com/docs/esign-rest-api/how-to/) from the [Docusign Developer Center](https://developers.docusign.com/), you merely need to install it by following the instructions below.

<a id="versionInformation"></a>
### Version Information
- **API version**: v2.1
- **Latest SDK version**: 5.0.0rc2

<a id="requirements"></a>
## Requirements
*   Python 2.7 (3.7+ recommended)
*   Free [developer account](https://go.docusign.com/o/sandbox/?postActivateUrl=https://developers.docusign.com/)

<a id="compatibility"></a>
## Compatibility
*   Python 2.7+

<a id="pathSetup"></a>
### Path setup:
1. Locate your Python installation, also referred to as a **site-packages** folder. This folder is usually labeled in a format of **Python{VersionNumber}**.  
    **Examples:**
    *   Unix/Linux: **/usr/lib/python2.7**
    *   Mac: **/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7**
    *   Windows: **C:\Users\{username}\AppData\Local\Programs\Python\Python37**
2. Add your Python folder’s path to your system as an environment variable.  
    **Unix/Linux:**
    1. Type the following command into your console: \
        **export PYTHONPATH = "${PYTHONPATH}:.:/_path_/_to_/_site-packages_"**
    2. Optionally, you can add this command to your system profile, which will run the command each time Python is launched.  

    **Windows:**
    <ol>
      <li>Open the Windows <strong>Control Panel.</strong></li>
      <li>Under the System and Security category, open the <strong>System</strong> information panel.</li>
      <li>Select <strong>Advanced System Settings</strong> to open the <strong>System Properties</strong> dialog box.</li>
      <li>On the <strong>Advanced</strong> tab, select the <strong>Environment Variables</strong> button at the lower-right corner.
          <ol style="list-style-type: lower-alpha">
              <li>Check to see whether <strong>PYTHONPATH</strong> has been added as a <strong>system variable.</strong></li>
              <li>If it has not, select <strong>New</strong> to add it. The variable you add is the path to the <strong>site-packages</strong> folder.</li>
          </ol>
      </li>
    </ol>


**Note:** If you are still unable to reference Python or pip via your command console, you can also add the path to the **site-packages** folder to the built-in environment variable labeled **Path**, which will take effect the next time you start your machine.

<a id="pip"></a>
### Install via PIP:
In your command console, type: **pip install docusign_esign**  
    **Note:** This may require the command console to be elevated. You can accomplish this via sudo in Unix/Linux, or by running the command console as an administrator in Windows.
