Welcome to the Wacom WILL Developer Documentation site

**In a continual effort to better serve our developers, we are in the process of making updates and improvements to the Wacom WILL Developer Documentation site. While visiting our site, you may notice inconsistencies in formatting and/or the naming and classification of our products and services. Please know that this is all temporary as we continue to improve our site and that we are doing our best to provide you with the most accurate and helpful information, sample code, and documentation. Thank you for your ongoing patience.**

The purpose of these pages is to provide supplementary technical information for software products downloaded from our primary developer website: https://developer.wacom.com

As a part of this initiative we are in the process of introducing the use of GitHub to host sample code. The first phase of using GitHub is with the Windows Signature SDK where sample code is no longer saved in these pages but found in the relevant GitHub repositories. This approach will be extended over time as we aim to improve the ease of use of our products.
