 # - web sockets to communicate with backend
 # - inline SVG used widely in buttons, widgets, etc.
 # - custom events used for most user interactions

 ---
 
 # Remove vs Delete
+
 Remove and Delete are quite similar, but can be frustrating if used inconsistently.
 
 ## Remove
+
 Take away and set aside, but kept in existence.
 
 For example:
-* Removing a user's permission
-* Removing a user from a group
-* Removing links between items
-* Removing a widget
-* Removing a link
-* Removing an item from a cart
+
+- Removing a user's permission
+- Removing a user from a group
+- Removing links between items
+- Removing a widget
+- Removing a link
+- Removing an item from a cart
 
 ## Delete
+
 Erase, rendered nonexistent or nonrecoverable.
 
 For example:
-* Deleting a field
-* Deleting a value in a field
-* Deleting a task
-* Deleting a group
-* Deleting a permission
-* Deleting a calendar event
+
+- Deleting a field
+- Deleting a value in a field
+- Deleting a task
+- Deleting a group
+- Deleting a permission
+- Deleting a calendar event
 
 # Add vs Create
+
 In most cases, Create can be paired with Delete, and Add can be paired with Remove.
 
 ## Add
+
 An already-exisiting item.
 
 For example:
-* Adding a permission to a user
-* Adding a user to a group
-* Adding links between items
-* Adding a widget
-* Adding a link
-* Adding an item to a cart
+
+- Adding a permission to a user
+- Adding a user to a group
+- Adding links between items
+- Adding a widget
+- Adding a link
+- Adding an item to a cart
 
 ## Create
+
 Something made from scratch.
 
 For example:
-* Creating a new field
-* Creating a new value in a field
-* Creating a new task
-* Creating a new group
-* Creating a new permission
-* Creating a new calendar event
+
+- Creating a new field
+- Creating a new value in a field
+- Creating a new task
+- Creating a new group
+- Creating a new permission

+# Our logo
 
-As a community, we are proud of our logo. Follow these guidelines to ensure it always looks its best. Our logo follows Google's material design spec and uses the blue interface color.
+As a community, we are proud of our logo. Follow these guidelines to ensure it always represents the identity of the Home Assistant project and community the best way possible.
 
 [Download Logo](https://github.com/home-assistant/assets/tree/master/logo)
 
-![Logo](/images/logo.png)
+![Logo](/images/brand/logo.png)
 
+Please note that this logo is not released under the CC license. All rights reserved.
 
-## Using the icon
+# Design
 
-Our icon is a shorter and most used version of our logo. The icon can exist without the wordmark, the wordmark should never exist without the icon.
+At the core of the Home Assistant logomark is the Blue House with Antenna, the three most recognizable and distinct features of the previous logo throughout the past decade.
 
-![Logo variants](/images/logo-variants.png)
+### Blue
 
-## Using the right variant
+Blue feels stable and essential. A bright sky blue is joyful, clear, and free of clouds.
 
-The pretty blue logo with a background shadow, pictured top left, is our primary logo. It should only be used with black, white, and non-duotone photography.
+### House
 
-When needed you can use our logo without a shadow, as seen as the second variant. 
+Of all possible combinations of shapes, a home is best abstracted in the shape of a structure with a pitched roof. With the vast amount of logos based on this shape, the best we can do is to make it more iconic. The house is further simplified - there is no gable and there is no chimney - to an orthogonal shape with an elegant and deliberate proportion.
 
-The outlined logo should only be used on packaging.
+### Antenna
 
-## Exclusion zone
+Call it a tree, a set of nodes, a PCB, or an antenna. The antenna is the most recognizable and memorable part of the previous Home Assistant logo, and is an easily understandable symbol that conveys technologies that are smart, connected, and growing evergreen.
 
-The logo needs some personal space. It's exclusion zone is equal to a quarter the height of the icon.
+# Usage
 
-![Clearspace](/images/clearspace.png)
+The default variation is the static colored wordmark in horizontal layout and dark text on a light background.
+
+## Layout variations
+
+![Logo layout variants](/images/brand/logo-layout-variants.png)
+
+The default layout is the wordmark in horizontal layout. It provides the clearest context to the brand identity of Home Assistant.
+
+Use the logomark variant when the context is clear that the logo is about Home Assistant. For example, inside the Home Assistant app where users are already aware of where they are at, the logomark variant without the wordmark can be used. The logomark can exist without the wordmark, however, the wordmark should never exist without the icon.
+
+Use the wordmark in vertical layout when the space available has an aspect ratio less than 4:3. For example, in a square space on a t-shirt where a logo is needed, since there is no established context of Home Assistant, the wordmark in vertical layout should be used.
+
+Lastly, use the wordmark in vertical layout with small logomark when Home Assistant is displayed in context of other Home Assistant-related projects. For example, in a flowchart showing the voice pipeline, use this layout for Home Assistant and its other related projects.
+
+## Color variations, backgrounds, and placement
+
+The default color is the colored version on light background with dark text.
+
+For backgrounds that are dark, for example, when it is used on a page in a dark theme, use the colored version on dark background with light text.
+
+In printed materials where color is unavailable, use the monochrome color variations.
+
+On background that are dark or photographic, use the light monochrome color on dark background variation.
+
+On backgrounds that are light or photographic, use the colored version. Do not use the monochrome variations.
+
+Do not enclose the logmark in a square or color or any confined backgrounds, except in specific situations enforced by another company's marketplace guidelines, for example, an iOS app icon.
+
+Do not add drop shadow to the logomark or the wordmark. If legibility is compromised due to the background, change the background to provide more contrast, or in last resort, add a heavily blurred drop shadaow.
+
+It should only be used with black, white, and non-duotone photography.
+
+Unlike the previous version of our logo, no outlined variants are available. Use the monochrome variants in those spaces.
+
+### Exclusion zone
+
+The logo needs some personal space. Its exclusion zone is equal to a quarter the height of the icon.
+
+![Space clearance for the wordmark](/images/brand/logo-exclusion-zone.png)
+
+## Animation
+
+The default is the static variant.
+
+Use the animated variant only for introductory purposes, for example, in the beginning of a video or on a loading screen.
+
+Use the animated with sound variant only when sound is warranted in the user's context. For example, use it in the beginning of a video since sounds are expected in a video, but do not use it on a loading screen since sounds are not expected in a user interface.
+
+Do not repeat the logo animation.
+
+## Sizes and app icon variants
+
+Special variants are created for specific contexts.
+
+Use the tiny variants when the logomark is used in a very small space (16x16 dp), for example, the favicon of the Home Assistant website, a notification on Android, or the menubar of macOS.

+- If users become unsure, they read the description. Make sure this explains what will happen.
+- Strive for minimalism.
 
 ## Buttons and X-icon
-* Keep the labels short, for example `Save`, `Delete`, `Enable`.
-* Dialog with actions must always have a discard button. On desktop a `Cancel` button and X-icon, on mobile only the X-icon.
-* Destructive actions should be a red warning button.
-* Alert or confirmation dialogs only have buttons and no X-icon.
-* Try to avoid three buttons in one dialog. Especially when you leave the dialog task unfinished.

 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>.
