How To Contribute To Sherlock

First off, thank you for the help!

There are many ways to contribute. Here is some high level grouping.

Adding New Sites

Please look at the Wiki entry on adding new sites to understand the issues.

Any new sites that are added need to have a username that has been claimed, and one that is unclaimed documented in the site data. This allows the regression tests to ensure that everything is working.

Adding New Functionality

Please ensure that the content on your branch passes all tests before submitting a pull request.
