ESP8266: Timed out waiting for packet header - arduino-uno

Question

Hi somebody who can link an beginners guide for ESP 8266 on arduino uno? Or help me with this error :
Arduino:1.8.9 (Windows 10), Kort:"Generic ESP8266 Module, 80 MHz,

If still. facing the issue try these settings
To Program Using Arduino Nano
Pin setup in nano:
Connect Nano GND pin to RST pin (ground to reset)
Pin setup in ESP-01
Connect GND to GPIO-0 (Initiates programming mode)
Connect VCC to CH_PD/CH_EN (Power pin to Chip Enable)
Pin setup between nano and ESP-01
Nano to ESP-01
Connect the VCC to VCC and CH_PD/CH_EN
Connect GND to GND and GPIO-0
Connect Tx to Tx
Connect Rx to Rx
