Permission denied while installing paraphone

Hi, when I try to follow the instructions in the file docs/data.md to install paraphone, I get the below error.

Cloning into 'paraphone'...

fatal: Could not read from remote repository.

Please make sure you have the correct access rights
and the repository exists.

Is the repository available publicly? Could you look into this, please? Thanks.
