Perry Gee – as discussed at the sprint meeting, can you take this on? I'm happy to help as necessary.

The minimum we need is:

• A README file which describes (briefly) what ngmix is and why users should care. This just needs to be a couple sentences.
• A doc directory following the layout shown at, for example, https://github.com/lsst/meas_extensions_photometryKron/tree/master/doc. We should add a little more detail than that provides though, since ngmix is not such a well established technique as Kron photometry. I think we'd be looking for a couple of paragraphs covering exactly what this plugin is useful for and how users can enable it.

Do you have time to review this one too?

This is essentially all documentation. I am unsure how the doc is supposed to be done, and would appreciate any comments.

Sure, I’ll take a look. Don’t forget to add a README file too.

I was unsure what format this README was suppposed to be in, but I have provided a few paragraphs in text format.

I am not really the right person to explain why someone would want to use this package. I think that more testing would be required for me to say. But as I understand from Jim, the two plugins we've provided are really precursors for more interesting plugins we may provide later. So trying to tell people why they would use this package may be premature.

The two review pieces are README and doc/mainpage.dox. I copied the style from meas_base/doc

I’ve left some comments on the PR. It looks like a good start considering that the package is still young.

All points in pull request answered.
