Documentation look unclear

[moolight-seashell]

The documentation doesn't seem very clear to me,

I've already had a bit of trouble finding this page :
https://pgchameleon.org/documents/usage.html#example

some lines are not executable as is,
but most of all I'm stuck here:

$ chameleon add_source --config default
/home/xy/.local/bin/chameleon.py:2: DeprecationWarning: pkg_resources is deprecated as an API. See https://setuptools.pypa.io/en/latest/pkg_resources.html
  from pkg_resources import get_distribution
You must specify a source name with the argument --source

$chameleon add_source --config default --source example
/home/xy/.local/bin/chameleon.py:2: DeprecationWarning: pkg_resources is deprecated as an API. See https://setuptools.pypa.io/en/latest/pkg_resources.html
  from pkg_resources import get_distribution
Traceback (most recent call last):

    exec(compile(open(__file__).read(), __file__, 'exec'))

    getattr(replica, args.command)()

                     ^^^^^^^^^^^^^^^^^^^^^^^^^^^^

                                 ~~~~~~~~~~~~^^^^^^^^^^^^^
KeyError: 'example'

for more detail, these line make my mysql not able to restart :

binlog_format= ROW
binlog_row_image=FULL
log-bin = mysql-bin
server-id = 1
expire_logs_days = 10

and i cannot run this as is :

CREATE USER usr_replica WITH PASSWORD 'replica';
CREATE DATABASE db_replica WITH OWNER usr_replica;

because of : CREATE DATABASE cannot run inside a transaction block
so this require to use psql and -c option
