47 | # Installation (ESP8266 Flasher - Easy way)
48 |
49 | 1. Download ESP8266 Flasher.
50 |
51 | 2. Download the release.bin file.
52 |
53 | 3. Open the ESP8266 Flasher and select the Node MCU port
54 |
55 | 
56 |
57 | 4. Then, go to the config tab and select the .bin file you've just downloaded.
58 |
59 | 
60 |
61 | 5. Finally, go back to the first tab and press "Flash"
62 |
63 | 6. Your Node MCU is ready!
64 |
65 | # Installation (Arduino IDE)
66 |
67 | 1. Open your Arduino IDE and go to "File -> Preferences -> Boards Manager URLs" and paste the following link:
68 | ``http://arduino.esp8266.com/stable/package_esp8266com_index.json``
69 | 2. Go to "Tools -> Board -> Boards Manager", search "esp8266" and install esp8266
70 | 3. Go to "Tools -> Board" and select you board"
71 | 4. Download and open the sketch "WiFi_Captive_Portal.ino"
72 | 5. You can optionally change some parameters like the SSID name and texts of the page like title, subtitle, text body...
73 | 6. Upload the code into your board.
74 | 7. You are done!
