Error in README.md

In README.md is a typo.

Correct version:

from ifirma.invoice import (Invoice, Customer, InvoicePosition, INVOICE_TYPE)
from ifirma.request import send_invoice

invoice = Invoice(
    invoice_type=INVOICE_TYPE.NON_VAT_PAYER,
    issue_date=datetime(...)
).with_issuer(
    'Imię Nazwisko'
).with_payed(
    float(price)
).with_comments(
    f"Nr zamówienia: {numer}"
).with_position(
    InvoicePosition(product_name, float(price))
).with_new_customer(
    Customer(full_name, email, zip, city, street1, street2)
)

You can also mention that after invoice creation, user should send it

create_invoice_response = send_invoice(invoice)
