 # SonOff module based on Mongoose-OS and using MQTT to integrate to some home automation
-# Setup via Web and in AP-mode
 
 ## Overview
 
 - Do not configure WiFi - leave the module in AP (Access Point mode).
 - Mongoose OS starts a WiFi network called `SONOFF_XXXXXX` with password
-- if STA is configured and gets access, the AP is disabled ~120 seconds after boot
+- if STA is configured and gets access, the AP is disabled ~120 seconds after boot `Sonoff`. Switch your workstation to that WiFi network
-`Sonoff`. Switch your workstation to that WiFi network
+
-- Point your browser to http://192.168.4.1
+## Setup via Web and in AP-mode
+
+- Point your browser to [http://192.168.4.1]http://192.168.4.1
 - You'll see a simple form to configure WiFi network & password and some sonoff parameters
 - Integration into your home automation system based on MQTT, please configure
-  - MQTT host
+  - MQTT host with port
-  - MQTT port
+  - MQTT Client ID
+  - MQTT Password
   - MQTT topic to send current switch status changes (published)
   - MQTT topic to subscribe to receive commands

-## How to install this app
+## How to build and install this app
 
 - Install and start [mos tool](https://mongoose-os.com/software.html)
 - Switch to the Project page, find and import this app, build and flash it:
