+===== Materials needed =====
+To do your very first Kniwwelino projects, you only need:
+  * 1 Kniwwelino
+  * 1 Micro USB cable
+  * 1 Computer
+{{:en:neededmaterials1.jpg?600|}}
+To be able to develop more complex projects, you can work with sensors and actuators like:
+  * An additional Kniwwelino (and Micro USB cable)
+  * A Powerbank
+  * A 3xAA or 3xAAA Battery holder
+  * LEDs
+  * External buttons
+  * Alligator clips in black, red and other colors
+  * Silicone wire in black, red and other colors (or any other wire)
+  * Small screws M2 or M2.5
+  * Tape
+{{:en:neededmaterials2.jpg?600|}}
+As soon as you understood you to use all the above can start working with:
+  * Potentiometer
+  * Temperature and humidity sensor
+  * Microphone
+  * Soil moisture sensor
+  * Light Sensor
+  * Hall effect sensor
+  * 3 axes Gyroscope and Axelerometer
+  * RGB and Gesture Sensor
+  * Motor
+  * Servo
+  * ...
+==== The Kniwwelino Board ====
+The Kniwwelino hardware consists of a 5x5 red LEDs matrix, a RGB LED and two push buttons. There are additional ports that can be used to extend the board by additional LEDs, buttons, sensors and other peripherals. The underlaying micro-controller platform is also embedding WiFi. That enables the Kniwwelino to connect itself to other Kniwwelinos over the Internet. A USB port enables to charge the board by plugging the cable on a computer, or using a charger (like the one used to charge smarpthones) or a power bank.

+==== The programming environment ====
+=== Online version ===
+You can program your Kniwwelino in different ways. The easiest way to start with is to use our visual programming tool Kniwwelino Blockly, which is available online on [[http://code.kniwwelino.lu]]. You can use it from any device with a web browser (e.g. a tablet), your code will be transfered to your Kniwwelino via Wifi.
+The visual programing tool allows you to create code by assembling blocks like puzzle pieces.

+{{:en:installation:interfaceweb_2_fen.png?800|}}
+=== Downloadable version ===
+Alternatively, to use Kniwwelino Blockly offline, you can download the [[en:installation|desktop version]]. With this version you can transfer the code to your Kniwwelino when attached via USB to your computer.
+=== Arduino IDE ===
+Advanced users can program the Kniwwelino with the Arduino IDE, with the help of our [[https://github.com/LIST-LUXEMBOURG/KniwwelinoLib|Kniwwelino Arduino Library]].
+==== The power source ====
+The Kniwwelino has no battery included. This means that you have to attach it to a power source to bring it to life. There are different possibilities for a power source.
+{{:en:chargers.jpg?600|}}
+You can either attach it via USB cable to the computer, or you can use a Powerbank, a USB Hub or a Micro USB based charger (as used for many mobile phones).
+{{:en:powerpc.jpg?200|}}{{:en:powerbank.jpg?200|}}{{:en:powerplug.jpg?200|}}
+As a more advanced user, you can also attach a Battery holder with 3 AAA or 3 AA batteries.
+As soon as you connect your Kniwwelino to such a power source, the RGB LED will start flashing, then all matrix LEDs will light up, and progressively switch off until the Kniwwelino has entirely booted (usually this will take a few seconds). During this time the Kniwwelino will try to connect to one of the WiFi Access Points it has been configured to previously.
+As soon as it is connected (or after a timeout, in case it cannot connect), the program which has last been transferred to the Kniwwelino will start.
