+# diogenes
+
+diogenes is a NixOS machine deployed on a Google VM. It hosts
+https://wpcarro.dev.
+
+## Deployment
+
+I manage diogenes's deployment with Terraform. My current workflow looks like
+this (highly subject to change):
+
+```shell
+cd /tmp/terraform # or any directory that hosts terraform state
+outpath=$(nix-build /depot -A users.wpcarro.nixos.diogenes)
+cp <out-path> .
+nix-shell -p terraform google-cloud-sdk # gcloud to authenticate if necessary
+terraform init/apply
+```
