first things first, you have to figure out how you want to control it?
you have two simple options...
1) connect a screen & keyboard
2) take advantage of the wonders of networking and use a remote access configuration
Word of advice... - Just because the Pi has HDMI your tv wont make a good display (esp if its only a 720p resolution like mine...), all it'll do is make your eyes hurt... in addition, if you run a remote access setup, you can just copy and paste all the code for the projects you see on here :)
Step 1
Plug it in!!! Turn it on!!!
If you have not done so already, wonder over here to work out how to set up a remote connection (sorry I have only catered for OSX - feel free to tell me I'm the anti Christ.. :P )
Remember the default Username is "Pi"
and the default Password is "Raspberry"
Step 2
The RasPi plead with you to set it up with the most basic of settings...
here comes your first syntax:
sudo raspi-config
The above will launch a configuration tool (see image below) which as a newbie you only need to tinker with a tiny little bit.
The 1st thing to do is to Expand the Filesystem - this allows any extra space on your SD card to be utilised by the OS if and when it requires.
The 2nd thing to do is to set the Internationalisation Options (see image below)... (now isn't that a big word...)
Setting your location just means that the RasPi knows where it is, and so it can tell you the time if you ever ask...
Finish... Reboot... And your done!!!
WooHoo!!
I promise these celebration will become more tactful... remember its a learning curve :)
