+# User Guide
+
+## Postgres
+
+This project relies upon several Postgres features that require elevated privileges.
+If you plan to use a _superuser_ when running migrations and working with the database,
+you can skip this section.
+
+It is best practice to _not_ use a superuser in most enterprise environments.
+For this reason, if you are configuring this in an environment
+where you do not possess these privileges,
+please work with your DBA to configure a new database in the following way:
+
+```sql
+-- Create a new database to store assets and relations.
+CREATE DATABASE IF NOT EXISTS assetdb;
+
+-- set the timezone to UTC
+ALTER DATABASE assetdb SET timezone TO 'UTC';
+```
+
+Reconnect to the `assetdb` database with the privileged user and run the following:
+
+```sql
+
+-- pg_trgm is required for to improve the performance of queries that use the LIKE operator.
+-- If you already have pg_trgm installed (extensions are global), you can skip this step
+-- If you don't know, you can run the following query to check:
+-- SELECT * FROM pg_extension where extname = 'pg_trgm';
+
+-- Install the pg_trgm extension on assetdb
+CREATE EXTENSION IF NOT EXISTS pg_trgm SCHEMA public;
+
+-- Create a user
+CREATE USER your_username WITH PASSWORD 'your_password';
+
+-- on Postgres 15, the public schema is not available except to superusers.
+GRANT USAGE ON schema public to your_username;
+
+-- Grant create permissions to your user on the public schema.
+GRANT CREATE ON schema public to your_username;
+
+-- Grant table modification permissions to your user on the public schema.
+GRANT ALL ON ALL TABLES IN SCHEMA public to your_username;
+
+```
+
+If you would like to keep the schema modifications separate from the collection user,
+you can create a separate user for this purpose.
