 9) Visual Studio Code & [Platform.IO](https://platformio.org/) Add-On are recommended!
 10) Optional: DS18B20 Sensors
 
+## Installation (Quick Start)
+Either clone the repository and build/upload yourself using Platformio and your IDE of choice or download the binaries and use esptool as follows:
+Example for Windows environments:
+```shell
+esptool.exe --after no_reset --chip esp32 --baud 921600 --port <Serial port of your device> write_flash --verify 0x10000 firmware.bin
+esptool.exe --after hard_reset --chip esp32 --baud 921600 --port <serial port of your device> write_flash 0x307000 littlefs.bin
+```
+
+The important part is the addresses `0x10000` for the firmware and `0x307000`for the filesystem.
+
+If everything went well you should see the following output on the console:
+```log
+Press the "BOOT" button within the next 5 seconds to enable Setup Mode!
+Setup Mode not enabled. You can enable it at every time by pressing the "BOOT" button once.
+[  5047][E][vfs_api.cpp:104] open(): /littlefs/configuration.json does not exist, no permits for creation

+Now you can connect to the AP ("CERASMARTER" network by default) and modify/import your configuration. A sample configuration is located [here](assets/Templates/Configurations/configuration.json)

+If MDNS is working properly on your end, you will be able to open the web UI using http://cerasmarter/
