ESP8266 Commands!

Hello!

I got my ESP8266 running and can communicate with it. I try to find the command list who is valid for the WiFi-module. But the explanations is to sloppy. Filled with Brackets, Qutoe Signs and spces that shall be there or not? I can list the WiFi networks that is on the air, but not connect to neighter of them. The module just says ERROR.

Can someone who knows the commands make a understandable list of commands. I am getting tired of guessing!

Not 100% sure how this is an ARDUINO issue ?

parameters in commnads are marked with <>, like and [] marks optional parameters

for example command AT+CWJAP_CUR=,,[][,<pci_en>]

example: AT+CWJAP_CUR="myssid","mypassword"

connects to AP (CWJAP is Configure WiFi Join Access Point)
parameters and <pci_en> are not mandatory, the example doesn't use them
