-Supply the board with 3.3V on VCC, best run with a voltage regulator that can deliver 300mA.
+Supply the board with 3.3V on VCC, best run it with a voltage source or regulator that can at least deliver 300mA (many arduino boards have 3.3V regulators on board, but they deliver less than 300mA).
 Initial testes just with a ftdi usb to serial converters show unstable wifi connections, sometimes even board startup is impossible (the esp8266 board draws too much current).

-<code>

 AT+RST - resets the board:
 ATE1 (verbose)
 ATE0 (non verbose)
-AT+CWMODE=1 access point mode
+AT+CWMODE=1 station mode (join an existing wifi network)
-</code>
+AT+CWMODE=2 access point mode (create a new wifi network)
+AT+CWMODE=3 access point mode + station mode (create a wifi and join an other one at the same time)
+AT+CWJAP="SSID","Your Password" (join a network with the ssid (visible name) and your wifi password)

+create a simple server:
+<source>
+AT+CIPMUX=1 (1: server accepts multiple connection, 0: single connections only)
+AT+CIPSERVER=1,80 (1: create 0:destroy server, 80: listening on port 80)
+</source>
+now you can try to connect to your server, eg with your browser.
+we need the ip address for that.
+find the ip of the board:

+AT+CIFSR

+other convenient tests:
+in the shell: telnet, netcat
+in puredata: netsend
