	=== Flashing Process Overview ~~(e.g for Tesla Charger)~~ ===		=== Flashing Process Overview ===
	[[File:Esp8266-flash.png\|thumb]]		[[File:Esp8266-flash.png\|thumb]]By default, when the module powers up it will be in FLASH boot mode (counterintuitively, this means the device will run code in its flash memory, not that the device is ready to be flashed). To flash code onto the module, it must be set instead into in UART boot mode. It's important to note, as the name implies, "boot modes" are set at boot (i.e. when the device is powered on), so they cannot be changed while when the device is running. To set the UART boot mode, hold the small pushbutton on the top side of the module down while you plug it in, this holds GPIO0 to ground and is the same process as the much-hated setting modes via solder blobs, but without the hassle. Unlike the solder blobs, which holds GPIO0 low until the blob is moved, you don't have to keep the pushbutton held down, so after plugging in the device with the button pushed, you can release it.

	~~# Solder GPIO0 to 0~~		==== Quick Method ====
	~~# Install & open Arduino and setup the code from https://github.com/jsphuebner/esp8266-web-interface~~
	~~# Flash the code (see below)~~
	~~# Re-solder GPIO0 to 1~~
