README: Overhaul everything, making usage more clear, add contributing
Adds CONTRIBUTING.md specifically for contributors, not users. Makes installing from npm the primary usage example. Compress the default configuration example. Removes a bunch of newlines to make editing easier. Uses better formatting for parameter lists.

### Secure Information
110+
### Supported environment variables
111+
112+
To avoid duplication of system or user specific information across several configuration files, use these environment variables:
164113

165-
To prevent checking in the BrowserStack `username` and `key` in your
166-
source control, the corresponding environment variables can be used.
114+
* `BROWSERSTACK_USERNAME`: BrowserStack user name.
115+
* `BROWSERSTACK_KEY`: BrowserStack key.
116+
* `TUNNEL_ID`: Identifier for the current instance of the tunnel process. In `TRAVIS` setup `TRAVIS_JOB_ID` will be the default identifier.
117+
* `BROWSERSTACK_JSON`: Path to the browserstack.json file. If null, `browserstack.json` in the root directory will be used.
167118

168-
The environment variables then can be safely provided in the build
169-
configuration. For example, with travis-ci you can follow:
170119

171-
http://about.travis-ci.org/docs/user/build-configuration/#Secure-environment-variables
120+
### Secure Information
172121

173-
## Running tests
174-
Run `browserstack-runner` to run the tests on all the browsers mentioned
175-
in the configuration.
122+
To avoid checking in the BrowserStack `username` and `key` in your source control system, the corresponding environment variables can be used.
176123

177-
You can include this in your test script to automatically run cross
178-
browser tests on every build.
124+
These can also be provided by a build server, for example [using secure environment variables on Travis CI](http://about.travis-ci.org/docs/user/build-configuration/#Secure-environment-variables).
