I need help, please help me.
i dont know how to install ruby on rails… and how i write a code in
the text editor and then save it…
please send me a link to a very good tutorial with full explanetion
and with photos.

Watch a couple of episodes

There are probably a bazillion tutorials out on the web (well, maybe
only a million). Google is your friend in this regard.

The forum members can’t really recommend anything specific because we
don’t know even what your OS is, and the specific install instructions
differ according to the OS.

And your post smacks of “no effort”.

What have you researched?

What have you tried?

Agree with Ar Chron…galharth please do some effort and you will get
everything and anything on google…Installation seems difficult but
actually it is not that difficult at all.
