I use an existing symfony project with sylius bundle and included payum bundle. I have already some bundle in the src folder.
I need to create a custom gateway. For this I found that : https://github.com/Payum/Payum/blob/master/src/Payum/Core/Resources/docs/develop-gateway-with-payum.md
But, what about where to execute the command line "composer create-project payum/skeleton", it seems to be important to apply new skeleton into current project ?
And then in the documentation, there are these informations :
Replace all occurrences of payum with your vendor name. It may be your github name, for now let's say you choose: acme
Replace all occurrences of skeleton with a payment gateway name. For example Stripe, Paypal etc. For now let's say you choose: paypal.
What does that mean ? replace all folder name, all file name, all terms in files ?
And finally, this documentation talks about : "Register a gateway factory to the payum's builder and create a gateway"
Where to do that ? How to do that ? Is there a command line or something like that ?
Many thanks
