 This provides a number of security benefits. First, secrets are not on disk. Secondly, users/operators never see the secrets fly by (passerbys or voyeurs that like to look over your shoulder when deploying to production)
 
+## Setting up the initial ATAT database
+
+This handles bootstrapping the ATAT database with a user, schema, and initial data.
+
+It does the following:
+
+- Sources the Postgres root user credentials
+- Source the Postgres ATAT user password
+- Runs a script inside an ATAT docker container to set up the initial database user, schema, and seed data in the database
+
+Requirements:
+
+- docker
+- A copy of the ATAT docker image. This can be built in the repo root with: `docker build . --build-arg CSP=azure -f ./Dockerfile -t atat:latest`
+- You need to know the hostname for the Postgres database. Your IP must either be whitelisted in its firewall rules or you must be behind the VPN.
+- You will need a YAML file listing all the CCPO users to be added to the database, with the format:
+
+```
+- dod_id: "2323232323"
+  first_name: "Luke"
+  last_name: "Skywalker"
+- dod_id: "5656565656"
+  first_name: "Han"
+  last_name: "Solo"
+```
+
+- There should be a password for the ATAT database user in the application Key Vault, preferably named `PGPASSWORD`. You can load this by running `secrets-tool --keyvault [operator key vault url] load -f postgres-user.yml` and supplying YAML like:
+
+```
+---
+- PGPASSWORD:
+    type: 'password'
+    length: 30
+```
+
+This command takes a lot of arguments. Run `secrets-tool database --keyvault [operator key vault url] provision -- help` to see the full list of available options.
+
+The command supplies some defaults by assuming you've followed the patterns in sample-secrets.yml and elsewhere.
+
+An example would be:
+
+```
+secrets-tool database --keyvault [operator key vault URL] provision --app-keyvault [application key vault URL] --dbname jedidev-atat --dbhost [database host name] --ccpo-users /full/path/to/users.yml
+```
