Discord analyzes GitHub pull requests and adds comments about incompatible CSS.

Follow these instructions to add Discord to your GitHub repository:

1. Navigate to Settings > Webhooks and Services
2. Add a webhook
   • Enter http://mdn-discord.herokuapp.com/hook as the Payload URL
   • Choose to select individual events. Ensure only Pull Request is selected.
   • Leave all other settings at their default values

To target specific browsers, add a .discord file to the root of your repository with Browserslist queries. For example:

ie >= 8, > 1%

Criteria can be separated by commas, newlines, or both.

Stylesheets will be tested against browsers that match any of the criteria. If the .discord file is empty or not present, Discord will default to testing against the two most recent versions of all supported browsers.

See TESTING.md for more information.

Discord is under development. Please report any problems on GitHub.
