Custom Branding of Desktop and Mobile Apps

Hi, everyone. We want to implement nextcloud on our website which is easy for us but we have problem with custom branding of Desktop sync, Android app and iOS app. I tried to download their codes from github but I don’t know how to edit and compile for our company. Can anyone explain or tell me sources where I can get information about it? If someone want to work with us in custom branding of these apps for our company, you can collaborate with us for a deal. Both options are open. Please help in this regard.


did you manage to do this @Bilal
