The HnD sourcecode which was not included in the v3 of the website, has been published on bitbucket: https://bitbucket.org/Solutionsdesign/hnd
Bitbucket uses mercurial as VCS, it's similar to git, but in our opinion more suitable for windows/.net development. We could hav chosen github as well, but we like mercurial, so we chose bitbucket.
There's a branch for v2.6, which is the current version also running here, and which is usable with llblgen pro v2.6. The active default branch is migrated to v3 of llblgen pro and will be developed further in the coming months.
If you want to participate in the HnD development, you can . Simply use mercurial and clone fork the repository, start developing your feature and offer us a pull request. We'll then review your change and pull it into our branch if it fits our coding standards and quality bar.
