DEV mode is only ever to be run locally, see the template's overview for instructions.

thank you brody, how can I add data collection then to my railway strapi app

• Deploy the template
• Eject the Strapi service in its service settings.
• Consultant the template overview for local setup steps.
• Once done with your changes locally, push the changes to Github.
• Railway will now automatically deploy the changes.

I am sorry 😔 I could not do that. Is there any tutorial for that. I just want to add some content to my production strapi. 3 day I couldn't do that

I'm sorry but I don't know how i could simplify the instructions further.
