Add documentation for deployment

[MrBowmanXD]

Add documentation in order to simplify the deployment proccess (e.g deployment to railway platform).

I can document the process that im doing in order to keep a reference for future use. (I'm currently using the railway platform)

That would be great, thanks.

Tried to deploy a ShinyCMS project in railway but i failed. Maybe i need a docker file. Will investigate tomorrow.

Well got it running in railway but had to copy a dockerfile and troubleshoot my way out. Had some questions related to host (is it a environmental variable?). I can't access the admin dashboard because of it i think.
