cut & paste commands to allow rmate installation

[sorbits]

You’re sourcing .bashrc from .bashrc? And you want people to append to .bashrc in their shell startup file?

Perhaps you meant to change the instructions to something that should be executed in a shell, though I don’t think we can really know what file to append the PATH modification to (there is a lot of flexibility when it comes to “shell startup”).

yes .bashrc is statistically the most present file across distribution .profile sometimes is missing.

anyway also ruby sometimes is missing to be honest I switched to rmate python since python si generally available across systems

thanks anyway for the time in reviewing the pull request.
