Expand the README

[khandelwal]

Flush out the README so that it's clear what's going on here.

What does this software do?
Why is it needed?
What's the micro-purchase experiment?

If one wants to run a local copy of this, how does one do it?

[khandelwal]

The new README doesn't explain what this repository is for, or what this software does. What are it's features? Why is new software required for a micro-purchase experiment?

[blacktm]

How about this:

This app will be used to manage bids for 18F's micro-purchase threshold experiment. Vendors will be able to view open issues and bid on them, given they have GitHub accounts and are registered on SAM.gov.

As we add features, we'll document them. Also, not sure what's expected for "why software is required" – because we don't want to do this manually? Seems weird to explicitly say that.

[khandelwal]

That sentence works. Let's add it in (but please pull request).

[blacktm]

So just to be clear, our policy is to never ever commit to master, no matter how trivial (I'm seriously asking)?

[khandelwal]

Yes!

LET IT BE SO.

Ok, so I've opened a PR to update the README at #26. What's the protocol for it merging into master? Do I have to wait for another member of 18F Consulting to review before merging, or can I self-review my own PR? If I'm confident in the PR and it passes all tests, can I merge the PR without review? With review, I'm I able to merge the PR myself, or should the the PR author never be allowed to merge their own PR?
