-                    Lovelace has many different cards. Each card allows the user
-                    to tell a different story about what is going on in their
-                    house. These cards are very customizable, as no household is
-                    the same.

+## Guidelines
+### Usage
+An alert displays a short, important message in a way that attracts the user's attention without interrupting the user's task.
+

+
+### Success alert
+Success alerts
+*Real world example coming soon*
+
+### Placement
+
+
+### Accessibility
+(WAI-ARIA: [https://www.w3.org/TR/wai-aria-practices/#alert](https://www.w3.org/TR/wai-aria-practices/#alert))
+
+When the component is dynamically displayed, the content is automatically announced by most screen readers. At this time, screen readers do not inform users of alerts that are present when the page loads.
+
+Using color to add meaning only provides a visual indication, which will not be conveyed to users of assistive technologies such as screen readers. Ensure that information denoted by the color is either obvious from the content itself (for example the visible text), or is included through alternative means, such as additional hidden text.
+
+Actions must have a tab index of 0 so that they can be reached by keyboard-only users.
+
+## Implementation
+
+### Example Usage
+**Alert type**
+
+<ha-alert alert-type="error">
+  This is an error alert — check it out!
+</ha-alert>
+
+<ha-alert alert-type="warning">
+  This is an warning alert — check it out!
+</ha-alert>
+
+<ha-alert alert-type="info">
+  This is an info alert — check it out!
+</ha-alert>
+
+<ha-alert alert-type="success">
+  This is an success alert — check it out!
+</ha-alert>

+  This is an error alert — check it out!
+</ha-alert>
+<ha-alert alert-type="warning">
+  This is a warning alert — check it out!
+</ha-alert>
+<ha-alert alert-type="info">
+  This is an info alert — check it out!
+</ha-alert>
+<ha-alert alert-type="success">
+  This is a success alert — check it out!
+</ha-alert>
+```
+
+**Title**

+</ha-alert>
+
+```html
+<ha-alert alert-type="success" title="Success">

+</ha-alert>
+
+```html
+<ha-alert alert-type="success" dismissable>
+  This is an success alert — check it out!
+</ha-alert>
+```
+
+**Slotted action**
+
+<ha-alert alert-type="success">
+  This is an success alert — check it out!
+  <mwc-button slot="action" label="Undo"></mwc-button>
+</ha-alert>
+
+```html
+<ha-alert alert-type="success">
+  This is an success alert — check it out!

+
+# Welcome to Home Assistant Design
+
+This portal aims to aid designers and developers on improving the Home Assistant interface. It consists of working code, resources and guidelines.
+
+## Home Assistant interface
+The Home Assistant frontend allows users to browse and control the state of their home, manage their automations and configure integrations. The frontend is designed as a mobile-first experience. It is a progressive web application and offers an app-like experience to our users. The Home Assistant frontend needs to be fast. But it also needs to work on a wide range of old devices.
+
+### Material Design
+The Home Assistant interface is based on Material Design. It's a design system created by Google to quickly build high-quality digital experiences. Components and guidelines that are custom made for Home Assistant are documented on this portal. For all other components check <a href="https://material.io" rel="noopener noreferrer" target="_blank">material.io</a>.
+
+## Designers
+We want to make it as easy for designers to contribute as it is for developers. There’s a lot a designer can contribute to:
+

+
+# How to edit design.home-assistant.io
+
+All pages are stored in [the pages folder][pages-folder] on GitHub. Pages are grouped in a folder per sidebar section. Each page can contain a `<page name>.markdown` description file, a `<page name>.ts` demo file or both. If both are defined the description is rendered first. The description can contain metadata to specify the title of the page.
+
+## Development
+
+You can develop design.home-assistant.io locally by checking out [the Home Assistant frontend repository](https://github.com/home-assistant/frontend). The command to run the gallery is `gallery/script/develop_gallery`. It will automatically open a browser window and load the development version of the website.
+
+## Creating a page
+
+Navigate to the [the pages folder][pages-folder] on GitHub. If the folder for your category does not exist yet, create it. Create a new Markdown file inside this folder for your description, ie `usability.markdown`. This filename will be used in the URL. Add the following content:
+
+```markdown
+---
+title: My new page
+---
+
+Hello and welcome to my new page!
+```
+
+Once saved, the page will be automatically added to the bottom of the sidebar. The title specified in the header will be shown as the page title and used in the sidebar.
+
+## Linking the page in the sidebar
+
+By default the sidebar will gather all pages and group them by category. You can override the order of the categories, define a name for categories and change the order of the pages in [`sidebar.js`](https://github.com/home-assistant/frontend/blob/dev/gallery/sidebar.js).
+
+Any category not listed in `sidebar.js` will be placed at the end of the sidebar.
+
+Any page not listed in `sidebar.js` will be placed at the end of its category.
+
+## Adding a demo to a page
+
+Create a file next to the description file with the same name as the description file, but with the `.ts` extension: `usability.ts`. For this example, we assume that the category folder that contains `usability.markdown` and `usability.ts` is called `user-experience`. Add the following content to `usability.ts`:
+
+```ts
+import { html, css, LitElement } from "lit";
+import { customElement } from "lit/decorators";
+import "../../../../src/components/ha-card";
+
+
+@customElement("demo-user-experience-usability")
+export class DemoUserExperienceUsability extends LitElement {
+  protected render() {
+    return html`
+      <ha-card>
+        <div class="card-content">
+          Hello world!
+        </div>
+      </ha-card>
+    `;
+  }
+
+  static get styles() {
+    return css`
+      ha-card {
+        max-width: 600px;
+        margin: 24px auto;
+      }
+    `;
+  }
+}
+
+declare global {
+  interface HTMLElementTagNameMap {
+    "demo-user-experience-usability": DemoUserExperienceUsability;
+  }
+}
+```
+
+Note that the demo deosn't need to render anything itself. It can also be used to declare web components to be used by the page description. Because page descriptions are using markdown, they can embed any HTML.
+
+## Publishing changes
+
+The website is automatically published whenever the source files in the `dev` branch change. So to get your changes published, open a pull request with your changes.

+Lovelace has many different cards. Each card allows the user to tell
+a different story about what is going on in their house. These cards
+are very customizable, as no household is the same.
+
+This gallery helps our developers and designers to see all the
+different states that each card can be in.
+
+Check [the Lovelace documentation](https://www.home-assistant.io/lovelace) for instructions on how to get started with Lovelace.
