Project Setup

Visual Studio is currently required. We have two main version, 2013 and 2010. You can pick up one of them below to start.


Helper Projects

  • ~~I'm moving most of the helpers to a new repository,~~All the active helpers are hosted at [s4pe-helper] because it is much easier to manage. However, most of them will be shipped with the S4PE build. * Currently DST and Thumbnail helpers are hosted there.

Without peter's help and work on s3pe/s3pi project, there won't be this project, which highly depends on his two projects. His philosophy to share and distribute open source project will be carried on.
