+PRs are always welcome, and we'll be happy to merge them if the test suite passes.
+
+To run the entire test suite would take a long time, so we've broken it down into various groups:
+
+``` shell
+TEST_TARGET=lint make test
+TEST_TARGET=unit make test
+TEST_TARGET=e2e make test
+TEST_TARGET=cov make test
+```
+
+All of these will be run by Travis, but you could save the ice caps from melting a little by running at least `unit` and `e2e` before you push.
+
+Our sole requirement is that organizations that want to extend API-Flow to support their format write both a parser and a serializer, and not simply a serializer.

 ## Documentation
-You can find more information about the internal structure of API-Flow in [src](https://github.com/luckymarmot/API-Flow/tree/develop/src). We've also created a set of templates to help speed up the extension process: [loader](https://github.com/luckymarmot/API-Flow/tree/develop/src/loaders/template/v1.0), [parser](https://github.com/luckymarmot/API-Flow/tree/develop/src/parsers/template/v1.0/), and [environment](https://github.com/luckymarmot/API-Flow/tree/develop/src/environments/template)
