+
+## About
+
+This add-on allows you to manage and program your ESP8266 and ESP32 based microcontrollers
+directly through Hass.io **with no programming experience required**. All you need to do
+is write YAML configuration files; the rest (over-the-air updates, compiling) is all
+handled by esphomeyaml.
+
+<p align="center">
+<img title="esphomeyaml dashboard screenshot" src="images/screenshot.png" width="700px"></img>
+</p>
+
+[_View the esphomeyaml documentation here_](https://esphomelib.com/esphomeyaml/index.html)
+
+## Example
+
+With esphomeyaml, you can go from a few lines of YAML straight to a custom-made
+firmware. For example, to include a [DHT22][dht22].
+temperature and humidity sensor, you just need to include 8 lines of YAML
+in your configuration file:
+
+<img title="esphomeyaml DHT configuration example" src="images/dht-example.png" width="500px"></img>
+
+Then just click UPLOAD and the sensor will magically appear in Home Assistant:
+
+<img title="esphomelib Home Assistant MQTT discovery" src="images/temperature-humidity.png" width="600px"></img>
+
+## Installation
+
+To install this Hass.io add-on you need to add the esphomeyaml add-on repository
+first:
+
+1. Add our Hass.io add-ons repository to your Hass.io instance. You can do this by navigating to the "Add-on Store" tab in the Hass.io panel and then entering https://github.com/hassio-addons/repository in the "Add new repository by URL" field.
+2. Now scroll down and select the "esphomeyaml" add-on.
+3. Press install to download the add-on and unpack it on your machine. This can take some time.
+4. Optional: If you're using SSL certificates and want to encrypt your communication to this add-on, please enter `true` into the `ssl` field and set the `fullchain` and `certfile` options accordingly.
+5. Start the add-on, check the logs of the add-on to see if everything went well.
+6. Click "OPEN WEB UI" to open the esphomeyaml dashboard. You will be asked for your Home Assistant credentials - esphomeyaml uses Hass.io's authentication system to log you in.
+
+**NOTE**: Installation on RPis running in 64-bit mode is currently not possible. Please use the 32-bit variant of HassOS instead.
+
+You can view the esphomeyaml docs here: https://esphomelib.com/esphomeyaml/index.html
+
+## Configuration
+
+**Note**: _Remember to restart the add-on when the configuration is changed._
+
+Example add-on configuration:
+
+```json
+{
+  "ssl": true,
+  "certfile": "fullchain.pem",
+  "keyfile": "privkey.pem"
+}
+```
+
+### Option: `ssl`
+
+Enables/Disables encrypted SSL (HTTPS) connections to the web server of this add-on. Set it to `true` to encrypt communications, `false` otherwise. Please note that if you set this to `true` you must also specify a `certfile` and `keyfile`.
+
+### Option: `certfile`
+
+The certificate file to use for SSL.
+
+**Note**: _The file MUST be stored in `/ssl/`, which is the default for Hass.io_
+
+### Option: `keyfile`
+
+The private key file to use for SSL.
+
+**Note**: _The file MUST be stored in `/ssl/`, which is the default for Hass.io_
+
+### Option: `leave_front_door_open`
+
+Adding this option to the add-on configuration allows you to disable
+authentication by setting it to `true`.
+
+## Embedding into Home Assistant
+
+It is possible to embed the esphomeyaml dashboard directly into
+Home Assistant, allowing you to access your ESP nodes through
+the Home Assistant frontend using the `panel_iframe` component.
+
+Example configuration:
+
+```yaml
+panel_iframe:
+  esphomeyaml:
+    title: esphomeyaml Dashboard
+    icon: mdi:code-brackets
+    url: https://addres.to.your.hass.io:6052
+```
