Unable to contribute code back to the project

```
Hi,

I'd like to make a number of proposals for code changes to this project, 
starting with the fact that there is no inheritance in any of the html 
templates making updating them a real pain.

Please can a wiki page be provided regarding how to contribute to the project?

Thanks,

Matt
