Why

Whenever we set up new infrastructure for a project, despite the fact that we have this infrastructure template to speed up the process, there is one part we still need to do manually (and repeatedly): documenting. Some common parts are the same for every infrastructure and can be generated as part of the template

• Managing environment variables
• Infrastructure diagram (There is a template on LucidChart)
• Connecting to remote DB via bastion instance
• How to use Terraform Cloud to plan and provision the new changes in a PR

The current documentation for the above parts can be borrowed from an existing project: https://github.com/worpt-wallet/wallet-api/wiki
