 So, I got a cheap NodeMCU board from eBay. Here are some notes to get started with the ESP8266 !

 Which means your board is working ! It's also included in the NodeMCU firmware repository
-### NodeMCU
+### NodeMCU release
+Download the last NodeMCU release from github: https://github.com/nodemcu/nodemcu-firmware/releases
+Check the image
+    ./esptool.py --port /dev/ttyUSB0 image_info ./nodemcu_float_0.9.6-dev_20150704.bin
+Should output something like
+    Entry point: 40100008
+segments
+    Segment 1: 31900 bytes at 40100000
+    Segment 2:  3064 bytes at 3ffe8000
+    Segment 3:     8 bytes at 3ffe8bf8
+    Checksum: 12 (valid)
+If it looks okay, proceeed to the next step, Flash !
+    ./esptool.py --port /dev/ttyUSB0 write_flash 0x00 ./nodemcu_float_0.9.6-dev_20150704.bin
+Wait until completion...
+    Connecting...
+    Erasing flash...
+    Writing at 0x00070c00... (100 %)
+    Leaving...
+Reset your board (powercycle). Connect using a serial app, like _picocom_
+    picocom /dev/ttyUSB0
+And you should be ready to go ! More info on NodeMCU usage, on the github page: https://github.com/nodemcu/nodemcu-firmware
+### Connect to your AP
+In the serial terminal:
+    wifi.setmode(wifi.STATION)
+    wifi.sta.config("SSID","password")
+    ip = wifi.sta.getip()
+    print(ip)
+Output is the current IP of your board. Open a new terminal and try to _ping_ it =)
+This setting is kept in flash I guess, since it still works after powercycling the board...
