Error(s) in README under "Usage from node"

[moos]

Issue description

Under calling params:

• ignore: should be a an array not a comma-separated string, e.g., ['scss', 'my/templates']
• ignorePattern is missing. Also an array.
• watch is missing
• noCssInject is missing

It may be better to just c&p the jsdocs in index.js.
