+## 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 idenfity 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](/twbs/bootstrap/labels).

+### Issues bots
+
+[@twbs-lmvtfy](https://github.com/twbs-lmvtfy) is a Bootstrap bot that hangs out in our GitHub issue tracker and automatically checks for HTML validation errors in live examples (e.g. jsFiddles, JS Bins, Bootplys, Plunks, CodePens, etc.) posted in issue comments. If it finds any errors, it will post a follow-up comment on the issue and point out the errors. If this happens with an example you've posted, please fix the errors and post an updated live example. If you opened a bug report, please check whether the bug still occurs with your revised, valid live example. If the bug no longer occurs, it was probably due to your invalid HTML rather than something in Bootstrap and we'd appreciate it if you could close out the GitHub issue.

     <p>When using tooltips or popovers on elements within a <code>.btn-group</code>, you'll have to specify the option <code>container: 'body'</code> to avoid unwanted side effects (such as the element growing wider and/or losing its rounded corners when the tooltip or popover is triggered).</p>

+    <h4>Ensure correct <code>role</code> and provide a label</h4>
+    <p>In order for assistive technologies – such as screen readers – to convey that a series of buttons is grouped, an appropriate <code>role</code> attribute needs to be provided. For button groups, this would be <code>role="group"</code>, while toolbars should have a <code>role="toolbar"</code>.</p>
+    <p>One exception are groups which only contain a single control (for instance the <a href="#btn-groups-justified">justified button groups</a> with <code>&lt;button&gt;</code> elements) or a dropdown.</p>
+    <p>In addition, groups and toolbars should be given an explicit label, as most assistive technologies will otherwise not announce them, despite the presence of the correct <code>role</code> attribute. In the examples provided here, we use <code>aria-label</code>, but alternatives such as <code>aria-labelledby</code> can also be used.</p>

In a couple places, we also use bleeding-edge CSS features that aren't yet fully standardized, but these are used purely for progressive enhancement.</p>
