Talking to a WiFi to Serial module

I've recently aquired a USR-WIFI232-T module that I'm using on a Digispark atiny dev board. And I've also ordered one of these little guys.

My main problem is that I don't have access to the wifi.h library, so I wondered if I could work around it by just using serial commands. Ultimately I'd like to have a simple web page that displays an analog pin.

I've read through a few tutorials but nothing quite gets were I need to be.

Does anyone have any suggestions or sample code?

I don't know the one from the first link, but the second is a esp8266.

I have made som notes on how to make a small webserver and flash firmware

There are lots of info on
