However, please do not use the official GitHub repository totestyour set. The sets contained in the repository are shipped toevery Chrome client, which takes real disk space and processing power on users' devices. Additionally, it would take some time to revert a RWS declaration if you discovered a problem with it during testing, as you can see. Sets should only be submitted to the public repository after you have tested them and you are certain that those are the changes you want every Chrome user to have.
