+# MozToggle
+
+`moz-toggle` is a toggle element that can be used to switch between two states.
+It may be helpful to think of it as a button that can be pressed or unpressed,
+corresponding with "on" and "off" states.
+
+```html story
+<moz-toggle pressed
+            label="Toggle label"
+            description="This is a demo toggle for the docs.">
+</moz-toggle>
+```
+
+## When to use
+
+* Use a toggle for binary controls like on/off or enabled/disabled.
+* Use when the action is performed immediately and doesn't require confirmation
+  or form submission.
+* A toggle is like a switch. If it would be appropriate to use a switch in the
+  physical world for this action, it is likely appropriate to use a toggle in
+  software.
+
+## When not to use
+
+* If another action is required to execute the choice, use a checkbox (i.e. a
+  toggle should not generally be used as part of a form).
+
+## Code
+
+The source for `moz-toggle` can be found under
+[toolkit/content/widgets/moz-toggle](https://searchfox.org/mozilla-central/source/toolkit/content/widgets/moz-toggle/moz-toggle.mjs).
+You can find an examples of `moz-toggle` in use in the Firefox codebase in both
+[about:preferences](https://searchfox.org/mozilla-central/source/browser/components/preferences/privacy.inc.xhtml#696)
+and [about:addons](https://searchfox.org/mozilla-central/source/toolkit/mozapps/extensions/content/aboutaddons.html#182).
+
+`moz-toggle` can be imported into `.html`/`.xhtml` files:
+
+```html
+<script type="module" src="chrome://global/content/elements/moz-toggle.mjs"></script>
+```
+
+And used as follows:
+
+```html
+<moz-toggle pressed
+            label="Label for the toggle"
+            description="Longer explanation of what the toggle is for"
+            aria-label="Toggle label if label text isn't visible"></moz-toggle>
+```
+
+### Fluent usage
+
+Generally the `label`, `description`, and `aria-label` properties of
+`moz-toggle` will be provided via [Fluent attributes](https://mozilla-l10n.github.io/localizer-documentation/tools/fluent/basic_syntax.html#attributes).
+To get this working you will need to specify a `data-l10n-id` as well as
+`data-l10n-attrs` if you're providing a label and a description:
+
+```html
+<moz-toggle data-l10n-id="with-label-and-description"
+            data-l10n-attrs="label, description"></moz-toggle>
+```
+
+In which case your Fluent messages will look something like this:
+
+```
+with-label-and-description =
+  .label = Label text goes here
+  .description = Description text goes here
+```
+
+You do not have to specify `data-l10n-attrs` if you're only using an `aria-label`:
+
+```html
+<moz-toggle data-l10n-id="with-aria-label-only"></moz-toggle>
+```
+
+```
+with-aria-label-only =
+  .aria-label = aria-label text goes here
+```
