Installation instructions are incomplete

[DDvO]

Hi, I wanted to give this interesting tool again a try,
but also this time have trouble installing it.

The README says just:

python3 -m venv venv
source venv/bin/activate
pip3 install .

but when following these steps the last command gives

ERROR: Directory '.' is not installable. Neither 'setup.py' nor 'pyproject.toml' found.

and the mentioned files and cli.py are nowhere to find.
The result is the same on Linux and MacOS.

Meanwhile I found that this is missing from the beginning of the instructions:

git clone git@github.com:polhenarejos/acme_email.git
cd acme_email
