 ## Sonoff-Tasmota
-Provide ESP8266 based Sonoff by [iTead Studio](https://www.itead.cc/) and ElectroDragon IoT Relay with Serial, Web and MQTT control allowing 'Over the Air' or OTA firmware updates using Arduino IDE.
 
-Current version is **5.12.0** - See [sonoff/_releasenotes.ino](https://github.com/arendst/Sonoff-Tasmota/blob/master/sonoff/_releasenotes.ino) for change information.
+Alternative firmware for _ESP8266 based devices_ like [iTead](https://www.itead.cc/) _**Sonoff**_ with **web**, **timers**, 'Over The Air' (**OTA**) firmware updates and **sensors support**, allowing control under **Serial**, **HTTP** and **MQTT**, so as to be used on **Smart Home Systems**. Written for Arduino IDE and PlatformIO.

-See [Wiki](https://github.com/arendst/Sonoff-Tasmota/wiki/Theo's-Tasmota-Tips) for background information.
+### Quick install
 
-### ATTENTION Version 5 and up
+Download one of the released binaries from https://github.com/arendst/Sonoff-Tasmota/releases and flash it to your hardware as documented in the wiki.
 
-These versions use a new linker script to free flash memory for future code additions. It moves the settings from Spiffs to Eeprom. If you compile your own firmware download the new linker to your IDE or Platformio base folder. See [Wiki > Prerequisite](https://github.com/arendst/Sonoff-Tasmota/wiki/Prerequisite).
+### Important User Compilation Information
 
-Best practice to implement is:
-- Open the webpage to your device
-- Perform option ``Backup Configuration``
-- Upgrade new firmware using ``Firmware upgrade``
-- If configuration conversion fails keep the webpage open and perform ``Restore Configuration``
+If you want to compile Sonoff-Tasmota yourself keep in mind the following:
 
-You should now have a device with 32k more code memory to play with.
+- Only Flash Mode **DOUT** is supported. Do not use Flash Mode DIO / QIO / QOUT as it might seem to brick your device. See [Wiki](https://github.com/arendst/Sonoff-Tasmota/wiki/Theo's-Tasmota-Tips) for background information.
+- Sonoff-Tasmota uses a 1M linker script WITHOUT spiffs for optimal code space. If you compile using ESP/Arduino library 2.3.0 then download the provided new linker script to your Arduino IDE or Platformio base folder. Later version of ESP/Arduino library already contain the correct linker script. See [Wiki > Prerequisite](https://github.com/arendst/Sonoff-Tasmota/wiki/Prerequisite).
+- To make compile time changes to Sonoff-Tasmota it can use the ``user_config_override.h`` file. It assures keeping your settings when you download and compile a new version. To use ``user_config.override.h`` you will have to make a copy of the provided ``user_config.override_sample.h`` file and add your setting overrides. To enable the override file you will need to use a compile define as documented in the ``user_config_override_sample.h`` file.
