Very little data on this so far, but thanks to jimmoy@ on Discord. Edits welcome.

• Create default Amazon Linux image
• Instance type t2.medium. It might work with t2.small, I didn't try it, t2.micro too small to build TM successfully
• As part of the creation process either configure keys for ssh so you can login and use the command line, or select one you already have
• Add Inbound rule for port 8080 to the security group so players can access it
• Install git, nvm, node, postgres client
• Clone the TM repo and follow the Local Setup instructions
• Get the game running on the default database, troubleshoot any mistakes from above
• Create RDS/Postgres instance
• Creation method "Easy" works, pick Aurora (PostgresQL Compatible) for the database
• Choose to let it set up EC2 connection, the defaults work
• Click Create database, don't take any "add-ons."
• Login to your EC2 instance
• The psql client should have been installed and you can use it to create the terraforming-mars database, see the Database wiki page in the repo
• The above page has the format of the POSTGRES_HOST entry and the info comes from the RDS instance page
