+Heyo, 
+
+The past year, I've had a growing need for a dashboard to check what's coming. 
+Lots of things to take care of for the baby, my girlfriend leaving couple days a month on average, keeping all family visits in mind, but also checking the weather of the day to know how to dress the little one. 
+Looks like having a baby requires you to get organized a little more :).
+
+Luckily, I had an old laptop screen laying around for such an occasion, and I had a couple Raspberries on the shelf. So I decided to get to the task. 
+
+## Getting the hardware together
+
+So the first thing to do was to get all the hardware needed for such a project: 
+
+* An old laptop screen
+* A raspberry pi, with a power cable
+* An inverter kit to convert the LDVS laptop output to HDMI such as [this one](https://www.ebay.com/itm/HDMI-DVI-VGA-Driver-LVDS-Inverter-Kit-Convert-a-Bare-Laptop-LCD-into-Monitor-/111115624120).
+* Another power cable to power the screen
+* An HDMI cable to connect the screen to the pi
+
+The cool thing with the inverter kit is that it will allow you to control the screen (brightness, on/off, ...).
+
+[Image of the buttons to control the screen]
+
+The inverter kit is pretty simple to connect : 
+
+* One input for the power cable
+* One input for the control board
+* One input for the actual screen signal conversion.
+
+You just have to be careful to choose the right type of inverter for your screen. 
+
+Once everything is connected, you essentially have a computer in front of you and the next step is to start working on the software side of things. 
+
+## Setting up the Raspberry
