-# Template Service
-
-This directory contains the code for the Template
-Service.
-
-## Database
-
-We use:
-
-- PostgreSQL 16 for the database. To run it, we use:
-  - Docker to run the database, as well as inject any user-defined
-    configurations or SQL files into the Docker image.
-  - Docker-Compose to run the database, as well as any other
-    services this API microservice may depend on.
-- [**Drizzle**](https://orm.drizzle.team/) for the ORM.
-
-Follow the instructions below for the setup, as well as to learn how to work with the database.
-
-### Setup
-
-1. Install Docker Desktop on your device. Launch it.
-
-2. To verify that it is launched and installed correctly, run the 
-  following in your terminal:
-
-    ```bash
-    docker --version
-    ```
-
-    If the command does not error, and outputs a version, proceed to
-    the next step.
-
-3. Inspect the `docker-compose.yml` file. It
-  should look like this:
-
-    ```yml
-    services:
-      # ...
-      postgres:
-        # ...
-        volumes:
-        - "template-db-docker:/data/template-db"
-        #  - ./init.sql:/docker-entrypoint-initdb.d/init.sql
-        ports:
-        - "5431:5432"
-        restart: unless-stopped
-
-    volumes:
-      template-db-docker:
-        external: true
-    ```
-
-    We observe that this Database relies on a 
-    Docker Volume. Replace all instances of 
-    `template-db-docker` with your desired 
-    volume name.
-
-4. Then, create the Docker Volume with
-  the following command:
-
-    ```bash
-    # in this case, the command is
-    # docker volume create template-db-docker
-    docker volume create <volume-name>
-    ```
-5. Finally, create the Database Container:
-
-    ```bash
-    docker-compose up -d
-    ```
-
-6. To bring it down, run this command:
-
-    ```bash
-    docker-compose down
-    ```
-
-### Schema
-
-We maintain the schema in the `src/lib/db/schema.ts` file.
-
-Refer to the Drizzle documentation to learn how
-to properly define schemas. Then, insert your
-schemas into the file.
-
-### Migration
-
-After you have created/updated your schemas in
-the file, persist them to the Database with
-Migrations.
-
-1. Configure your credentials (port,
-    password, ...) in:
-
-    - `drizzle.config.ts`
-    - `drizzle.migrate.mts`.
-    - `src/lib/db/index.ts`.
-
-    In the future, we may wish to migrate these
-    credentials to environment variables.
-
-2. Run the `npm run db:generate` command to
-generate your `.sql` Migration Files under the
-`drizzle` folder.
-
-3. Rename your
-    `<migration_num>_<random_name>.sql` file
-    to `<migration_num>_<meaningful_name>.sql`.
-
-    For example:
-    - Generated: `0000_dazzling_squirrel.sql`
-    - Renamed: `0000_initial_schema.sql`.
-
-    Then, rename the
-    `meta/_journal.json` tag from
-    `0000_dazzling_squirrel` to
-    `0000_initial_schema` as well. Replace the
-    migration number and name with the one you
-    used.
-
-4. Finally, run the migration with this:
-
-    ```bash
-    npm run db:migrate
-    ```
-
-### Connecting with the DB
-
-1. Import the `db` instance from `lib/db`.
-2. Use the Drizzle APIs and the tables defined in
-    `src/lib/schema.ts` to interact with the
-    tables.
-
-    ```ts
-    import { db, tableName } from '../lib/db';
-
-    const route = async (req, res) => {
-      await db.select().from(tableName); //...
-    }
-    ```
