I am an absolute newcomer to the Raspberry Pi world. I have just bought a Pi3 and am looking to learn the basics from the bottom up.
I have the operating software installed and working and next thing I am looking to do is to have, the chromium browser for example, start on initial power on.
I have tried reading in to this but still feel swamped about how many different ways there are to do this, via different file routes.
Which method is the simplest to be walked through and also the least stressful on the computer itself? I have tried already in editing the autostart file but am being shown an error on trying to save this, being told that I "Can't open the file to write".
Thanks in advance for the help
