 1. Install and run postgres.
 2. Create postgres user and database (and add uuid extension while you're there 
    ):
-    createuser shopkeeper
-    createdb shopkeeper
-    sudo -u postgres -i psql
-    postgres=# ALTER DATABASE shopkeeper OWNER TO shopkeeper;
-    \password shopkeeper
-    postgres=# CREATE EXTENSION IF NOT EXISTS "uuid-ossp";

 3. Save password somewhere safe and then and add a `.env` file to the project 
    directory with the contents:
-    DATABASE_URL=postgresql://shopkeeper:<password>@localhost/shopkeeper
-    RUST_LOG="shopkeeper=debug"
-    HOST="http://localhost:3030"
+```
+DATABASE_URL=postgresql://shopkeeper:<password>@localhost/shopkeeper
+RUST_LOG="shopkeeper=debug"
+HOST="http://localhost:3030"

 4. Create a new file at `src/db/refinery.toml` with the contents:
-    [main]
-    db_type = "Postgres"
-    db_host = "localhost"
-    db_port = "5432"
-    db_user = "shopkeeper"

 # Todo
 
-* Add HTTP header authentication for endpoints that modify an owner's data.
-* Add DELETE endpoints for existing resources.
+* Add update endpoints.
 * Add endpoints for the other models.
-* Add caching. Not sure how to do this exactly. Could use Redis, Varnish, Nginx, 
-  or a lib resident in the rust web server process. I'll probably need to do 
-  invalidations as transactions are made, or interiors are updated.
 * Make self-contained docker container that can run the app without any setup.
 * Add rate-limiting per IP address. The `tower` crate has a service that might 
   be useful for this.
