-With both methods, you can use now /usr/local/bin/leap, which in most cases will be in your $PATH.
+The `--user-install` option for `gem` will install gems to a location in your home directory (handy!) but this directory is not in your PATH (not handy!). Add the second line to your `.bashrc` file so that all your shells will have `leap` in PATH.
