+# RGB strip WiFi server
+
+This server has been tested with:
+* ws2812b LED strip
+* WeMos ESP8266 board
+
+
+# Instructions
+
+The first time it boots, the board will create its own access point so you can configure the SSID and password.
+To configure it, just connect to the `led` network and access the board either using its IP (it is the default gateway for the network) or its MDNS name (`esp8266.local`):
+
+```
+curl http://esp8266.local/credentials?ssid=mywifi&pass=mypassword
+```
+
+The board will then reboot and try to log in with the given credentials.
+If the credentials were correct, the `led` network should have disappeared.
+If it hasn't, try rebooting the board or debugging.
+
+Once the board is connected to your router, you can start using the API of the board.
+
+# API
+
+* `/clear` clear WIFI credentials
+* `/credentials?ssid=<SSID>&pass=<PASSWD>` Set the
+* `/color?r=<R>&g=<G>&b=<B>` Set 
+* `/off` turn off the lights
+* `/on` turn on the lights (using the last color and value)
+* `/toggle` turn the lights if they are off, and vice versa
+* `/white` set the color to white
+* `/brightness?value=<VALUE>` set the brightness value (0-255)
+* `/brightness/up` turn up the brightness (up to 255)
+* `/brightness/down` turn down the brightness (down to 255)
+
+# Debugging
+You can use a serial monitor (e.g. in the Arduino IDE) to connect to the board.
+
+# Over-the-air updates
+
+You can connect to your board wirelessly and update its firmware using OTA updates.
+To do so, follow this instructions: http://esp8266.github.io/Arduino/versions/2.0.0/doc/ota_updates/ota_updates.html
