The samples/ directory contains lots of useable templates that might help others using your new features. Keep them less specific as possible (for instance use environment variables to allow others to use it directly without relying on a specic path in KV).
Read first TemplateAPI.md to ensure you are using the best functions for the job, the API is kept compact and powerful with many examples.
All the samples are unit-tested, so launch rspec before commiting, a template not converging will not be merged.
Report it, but read carefully TemplateAPI.md and README.md
Contributions in code are welcomed, create a fork and then a Pull Request, we will review it quickly.
