docs: update docs to reflect current dev process

CONTRIBUTING just refers to README.rst now, and I've removed all references to
`tox` since it's no longer in use.

 Thanks for helping out!  I'll make every effort to respond to PRs in a relateively short time, once the CI has passed, at least.
 
 ## Development Environment
-### Requirements
-- virtualenv >= 16.7.3 `pip install virtualenv` or `pip install --user virtualenv`
-### Enivronment
-```
-$ git clone git@github.com:wwade/jobrunner.git
-$ cd jobrunner
-$ . testenv
-(venv27)$ 
-```
-### Running Tests
-The full CI test suite
-```
-(venv27)$ tox
-```
-Individual tests can be executed with `nosetests` or `pytest`.  A coverage report for unit tests can be created by running `./cover.sh` from inside the virtualenv.
-To just run unit tests, you can skip the integration tests with `nosetests`:
-```
-(venv27)$ nosetests -e integration
-```
+See [README.rst](README.rst).
 
 ## Guidelines
 1. Please try to keep PRs on a single topic.  Generally this means that they'll invlove a "small" number of commits, and that each commit contains the minimal changes for its purpose.
