Upgrading a package in ELPA (ergoemacs-mode)

[Eric A. Wayman]

Hello,

I would like to upgrade a package in ELPA, ergoemacs-mode. The 
version
in ELPA is years out of date and doesn't work.

The maintainer of this package, Matthew Fidler, has said it would 
be okay
for me to handle the upgrading of the package in ELPA. But I don't
know how to do this and I'm not sure if I'm allowed to since I'm 
not the
official maintainer.

Could you let me know if it's possible for me to upgrade the 
package in
ELPA myself, and if so, how?

By the way, the official repository is
https://github.com/ergoemacs/ergoemacs-mode . The code there works 
well
in Emacs 26.1

Thank you and best regards,
Eric A. Wayman
