 ## Important User Compilation Information
 If you want to compile Tasmota yourself keep in mind the following:
 
+- For ESP8285 based devices only Flash Mode **DOUT** is supported. Do not use Flash Mode DIO / QIO / QOUT as it might seem to brick your device.
+- For ESP8285 based devices Tasmota uses a 1M linker script WITHOUT spiffs **1M (no SPIFFS)** for optimal code space.
 - To make compile time changes to Tasmota use the `user_config_override.h` file. It assures keeping your custom settings when you download and compile a new version. You have to make a copy from the provided `user_config_override_sample.h` file and add your setting overrides.
