+## Issues and labels
+
+Our bug tracker utilizes several labels to help organize and identify issues. Here's what they represent and how we use them:
+
+- `browser bug` - Issues that are reported to us, but actually are the result of a browser-specific bug. These are diagnosed with reduced test cases and result in a issue opened on that browser's own bug tracker.
+- `confirmed` - Issues that have been confirmed with a reduced test case and identify a bug in Bootstrap.
+- `css` - Issues stemming from our compiled CSS or source Less files.
+- `customizer` - Issues with our web-based Customizer.
+- `docs` - Issues for improving or updating our documentation.
+- `examples` - Issues involving the example templates included in our docs.
+- `feature` - Issues asking for a new feature to be added, or an existing one to be extended or modified. New features require a minor version bump (e.g., `v3.0.0` to `v3.1.0`).
+- `grunt` - Issues with our included JavaScript-based Gruntfile, which is used to run all our tests, concatenate and compile source files, and more.
+- `help wanted` - Issues we need or would love help from the community to resolve.
+- `js` - Issues stemming from our compiled or source JavaScript files.
+- `meta` - Issues with the project itself or our GitHub repository.
+
+For a complete look at our labels, see the [project labels page](https://github.com/twbs/bootstrap/labels).

 [@twbs-rorschach](https://github.com/twbs-rorschach) is a Bootstrap bot that hangs out in our GitHub issue tracker and automatically checks all pull requests for a few simple common mistakes. It's possible that Rorschach might leave a comment on your pull request and then close it. If that happens, simply fix the problem(s) mentioned in the comment (there should be link(s) in the comment explaining the problem(s) in detail) and then either:
 
 * Push the revised version to your pull request's branch and post a comment on the pull request saying that you've fixed the problem(s). One of the Bootstrap Core Team members will then come along and reopen your pull request.
 * Or you can just open a new pull request for your revised version.
 
+[@twbs-savage](https://github.com/twbs-savage) is a Bootstrap bot that automatically runs cross-browser tests (via [Sauce](https://saucelabs.com) and Travis CI) on JavaScript pull requests. Savage will leave a comment on pull requests stating whether cross-browser JS tests passed or failed, with a link to the full Travis build details. If your pull request fails, check the Travis log to see which browser + OS combinations failed. Each browser test in the Travis log includes a link to a Sauce page with details about the test. On those details pages, you can watch a screencast of the test run to see exactly which unit tests failed.
