i dont understand the point theres a software to make automated config but on website it is written that the software is beta and not to use for production so i can create my own signing request by openssl but no idea where to upload it and get my certificate
Have a look at the list of client implementations if you don’t want to run the official one.
CSR’s can be handeled by the --csr option of the official client.
i mean ccant i just get the certificate by email like normal ssl providers do and the rest, configure by myself
Yes, that is correct, you have to use a client speaking the ACME protocol to submit your CSR and download the certificate.
