At present, Chapel has three main documents with information about contributing to the project:

From working on other open-source projects recently that have similar cases of what seem like semi-redundant or partially overlapping documentation, it seems like it would be nice to reduce this list to just one or two documents about contributing. “One” seems in many ways ideal, though I could also imagine an approach in which contained just the basics and pointed to a second document which went through it in more detail. And this might be preferable to having say it all.
