• Connected Leap Motion controller
• Installed Leap Motion SDK 1.0.8.7665 for Windows
• Installed Visual Studio 2012 or Visual Studio Express 2012 for Windows Desktop
• OS: Windows 8
  (It may be that the patched app will be runnable on other OS which supported by putty, but I have never run it on except Windows 8.)

1. Download official PuTTY archive.
   http://www.chiark.greenend.org.uk/~sgtatham/putty/download.html
   (Source code -> Windows source code -> Release source code for Windows)
2. Extract archive to local storage.
3. There are two options to apply the patches.
4. Overwrite "putty-src" directory of this repository to "putty-src" directory of extracted files. (Recommend)
5. Apply "Add-Leap-Motion-feature.patch" using patch command.
6. Set environment variable "LEAP_SDK" to point the "LeapSDK" (not "LeapDeveloperKit") directory of installed Leap Motion SDK.
   Example:
   Set envrionment variable
7. Open putty-src\WINDOWS\MSVC\PUTTYGEN\PUTTYGEN.sln by Visual Studio.
8. Build and run.

The same license as original PuTTY.
