I added the following directories
(I manually copied from GitHub /Transportersio/omnipay-square and add it to the directory. Not using composor)
The Microweber read this module and created the following SQL entry
(103, '2020-05-12 22:59:34', '2020-05-11 19:31:43', NULL, 1, 1, 'Square payment', 0, NULL, 'shop/payments/gateways/omnipay_square', NULL, 'https://microweber.org/userfiles/modules/shop/payments/gateways/omnipay_square/omnipay_square.png', 'Microweber', NULL, NULL, 'payment_gateway', 1, 0, 132, NULL, 1, 0, NULL, 0, NULL, NULL, NULL, 'online shop');
Are there any other things I must create in the system?
