+## What this repo gives you
 
-This repo contains the **support files** around the dbt project: templates, TODO stubs, and the autograder. It deliberately does **not** contain `dbt_project.yml`: creating the project is Task 1, and you do it yourself with `dbt init`.
+This repo is a **ready-to-run dbt project**: the project config is wired up and every model, test, and report is a TODO stub for you to fill in. You do not scaffold anything: your job is to write the models, tests, and docs.

-## Task 1: create the dbt project into this repo
+## Task 1: connect to the shared database
 
-`dbt init` always generates a new subfolder, so create the project next to this repo and move its `dbt_project.yml` in:
-
-```bash
-# from inside this repo
-dbt init nyc_taxi_borough_daily --skip-profile-setup
-mv nyc_taxi_borough_daily/dbt_project.yml .
-rm -rf nyc_taxi_borough_daily/
-```
-
-Deleting the generated folder also removes the `models/example/` scaffolding the assignment warns about. Then open `dbt_project.yml` and remove the `example:` block under `models:`.
-
-## Connect to the shared database
+The project is already initialised, so Task 1 is just pointing it at the database with your personal schema.
 
 1. Copy the connection template and set your personal schema:
