Dear Atlury,

I have just loaded noobs and have created a media server. Now I want to use the PI3 wifi as Access point. The code looks very useful. Now please tell me,

1. how should I use this code in Terminal of PI3. Should I copy and paste the entire code in terminal?
2. It seems you have created IP address of PI-AP as 10.0.0.1 is it correct? Will remail static IP for PI-AP?

I am novice in PI coding etc. If I am asking some silly question, please forgive me.
