 This is made very easy, I think, by the STorM32's ESP firmware. The modified .js and .css (and even . htm) files just need to be uploaded to the ESP, as described before in the chapter [[#Installation|Installation]]. Even better for development, one can set options in the storm32web.cfg file such that the .js and .css files are fetched from your private web space, which makes the development cycle very fast. See storm32web.cfg for details.

	The ESP8266 requires 3.3 V, but is quite power hungry and attention needs ~~thus~~ be paid to the power scheme. The average power consumption is ~~actually~~ not critical, the ESP8266 however consumes the power in burst of up to several 100 mA, and the power supply must be able to handle that.

	The ESP8266 Wifi module in the list is obvious. If you are using a v1.x STorM32 board, when ~~you need in addition~~ a USB-to-serial adapter. It is required for flashing the ESP8266 module with a dedicated firmware and upload other files to the ESP8266. However, you probably have one anyhow. For STorM32 v3.x boards ~~this~~ is not needed.

	It is important to get the correct ESP8266 module. Quite many different versions are available, see e.g. [http://www.esp8266.com/wiki/doku.php?id=esp8266-module-family]. You need a module with '''''1 MB (8 Mb)''''' flash, since the STorM32's ESP firmware is made for that flash size.		It is important to get the correct ESP8266 module.
