+Start the UF2 Bootloader
7
+
8
+Nearly all CircuitPython boards ship with a bootloader called UF2 (USB Flashing Format) that makes installing and updating CircuitPython a quick and easy process. The bootloader is the mode your board needs to be in for the CircuitPython .uf2 file you downloaded to work. If the file you downloaded that matches the board name ends in uf2 then you want to continue with this section. However, if the file ends in .bin, you have to do a more complex installation - go to this page for details.
9
+

+Espressif Boards without UF2 Bootloaders
11
+
12
+See [this page](https://learn.adafruit.com/circuitpython-with-esp32-quick-start/installing-circuitpython) for how to load a .bin file on an ESP32 or ESP32-C3 board.

19
+
20
+The next step is to write your credentials to settings.toml. Make sure your board is running CircuitPython. If you just installed CircuitPython, you may to reset the board first.

+You can edit files by going to http://000.0.0.0/code/.
25
+
26
+If the keys CIRCUITPY_WIFI_SSID and CIRCUITPY_WIFI_PASSWORD are set in settings.toml, CircuitPython will automatically connect to the given Wi-Fi network on boot and upon reload.

+This demo is designed to run on the Kaluga, but you can adapt it
9
+to other boards by changing the constructors for `bus` and `cam`
10
+appropriately.
11
+
12
+The camera is placed in YUV mode, so the top 8 bits of each color
13
+value can be treated as "greyscale".
14
+
15
+It's important that you use a terminal program that can interpret
16
+"ANSI" escape sequences. The demo uses them to "paint" each frame
17
+on top of the prevous one, rather than scrolling.
18
+
19
+Remember to take the lens cap off, or un-comment the line setting
20
+the test pattern!
