up: arch Meets hello-world next: Creating a New Archive prev: arch Commands in General

The first step to using arch is to set your id with a command like:

            % tla my-id "Tom Lord <lord@emf.net>"

Your id should be your name, followed by your email address in angle brackets.

`arch` records your id in various log messages that it creates.

You can find out your id with:

            % tla my-id
            Tom Lord <lord@emf.net>

### How it Works -- Your arch Id

After the command above, you will have some new files in your home directory:

            % ls ~/.arch-params
            =id

            % cat ~/.arch-params/=id
            Tom Lord <lord@emf.net>

Caution: You usually should not edit files in `~/.arch-params/` "by hand."
