 # NixOS AMIs

 [![OpenSSF Scorecard](https://api.securityscorecards.dev/projects/github.com/arianvp/amis/badge)](https://securityscorecards.dev/viewer/?uri=github.com/arianvp/amis)
 
 Temporary home for the soon to be official NixOS AMIs
 
-## Costs and Sponorship
+## Setting up account
+
+Some steps need to be done manually to set up the account.  This is a one time
+process. These are hard to automate with Terraform.
+
+First opt in to all regions:
+
+```bash
+nix run .#enable-regions
+```
+
+Then request a quota increase for the number of AMIs you want to publish.
+This will create support tickets in all regions.  You can check the status
+of the tickets in the AWS console. It might take a few days for the tickets
+to be resolved.
+
+```bash
+nix run .#request-public-ami-quota-increase -- --desired-value 1000
+```
 
-Testing all this and storing all the AMIs whilst I figure out moving this to the
-NixOS Foundation costs me non-significant amount of money.  If you think this
-cause is worthwhile please consider sponsoring me through Github Sponsors.
+Finally enable public AMIs:
 
-Each image is `4GB`  in size at the moment. EBS Snapshots cost  `$0.05` per GB
-per month. So each image costs `$0.20` per month to store.  We replicate  across
-all 32 AWS regions so that's `$6.40` per month per image.
+```bash
+nix run .#disable-image-block-public-access
+```
