+              Hi there! I'm the esphomeyaml setup wizard and will guide you through setting up
+              your first ESP8266 or ESP32-powered device using esphomeyaml.
+            </p>
+              <a href="https://www.espressif.com/en/products/hardware/esp8266ex/overview" target="_blank">ESP8266s</a> and
+              their successors (the <a href="https://www.espressif.com/en/products/hardware/esp32/overview" target="_blank">ESP32s</a>)
+              are great low-cost microcontrollers that can communicate with the outside world using WiFi.
+              They're found in many devices such as the popular Sonoff/iTead, but also exist as development boards
+              such as the <a href="https://esphomelib.com/esphomeyaml/devices/nodemcu_esp8266.html" target="_blank">NodeMCU</a>.
+            <p>
+            </p>
+              <a href="https://esphomelib.com/esphomeyaml/index.html" target="_blank">esphomeyaml</a>,
+              the tool you're using here, creates custom firmwares for these devices using YAML configuration
+              files (similar to the ones you might be used to with Home Assistant).
+            <p>
+            </p>
+              This wizard will create a basic YAML configuration file for your "node" (the microcontroller).
+              Later, you will be able to customize this file and add some of
+              <a href="https://github.com/OttoWinter/esphomelib" target="_blank">esphomelib's</a>
+              many integrations.
+            <p>
+            <p>
+              First, I need to know what this node should be called. Choose this name wisely, changing this
+              later makes Over-The-Air Update attempts difficult.
+              It may only contain the characters <code class="inlinecode">a-z</code>,
+              <code class="inlinecode">0-9</code> and <code class="inlinecode">_</code>

+              Great! Now I need to know what type of microcontroller you're using so that I can compile firmware for them.
