After installing issho, you will want to do some setup.

First, add the machine you want a profile for to your .ssh/config. For example, if you want to add a machine with the alias dev (the default for issho), you would add the following lines to your ssh config.

Host dev
    Port XXXXX
    User your_user

Once this is set up, you can set up passwords and common variables using the following command:

issho config dev

This command will drop you into an interactive prompt where you can enter passwords and configuration variables.
