+# Jaffle Shop — altimate-code starter sample
+
+Everything below runs against a local DuckDB file — no cloud warehouse, no
+credentials, no network calls.
+
+## What's in here
+
+```
+dbt_project.yml         dbt project config
+profiles.yml            DuckDB profile — path is project-relative
+sample-manifest.json    version metadata used by altimate-code to detect
+                        stale copies on upgrade
+models/
+  staging/
+    stg_customers.sql   renames raw customer columns to snake_case
+    stg_orders.sql      renames raw order columns
+    schema.yml          column descriptions + unique/not_null tests
+  marts/
+    customers.sql       one row per customer, joins in order counts
+    orders.sql          one row per order, joins in customer names
+    schema.yml          column descriptions + tests + relationships
+seeds/
+  raw_customers.csv     3 rows of test data
+  raw_orders.csv        4 rows of test data
+target/
+  manifest.json         PRE-COMPILED dbt manifest — ships with the sample so
+                        altimate-code's static workflows (/discover, /review)
+                        work without dbt-core / dbt-duckdb installed
+```
+
+## What to try (works with zero external tools)
+
+- `/discover stg_customers` — walk the DAG and see what depends on this model
+- `/review models/marts/customers.sql` — run the reviewer against a mart model
+- Open any `.sql` file and ask altimate-code to explain the transformation
+- Ask altimate-code "what tests would you recommend for `orders`?"
+
+## What to try (needs `dbt-core` + `dbt-duckdb` installed)
+
+```bash
+pip install dbt-duckdb
+cd ~/altimate-sample-dbt         # or wherever you materialized the sample
+dbt seed                          # load the CSVs into DuckDB
+dbt build                         # run models + tests
+duckdb target/jaffle.duckdb -c 'select * from customers'
+```
+
+Once `dbt-duckdb` is on your `$PATH`, altimate-code detects it automatically
+and the "run" workflows appear in `/help`.
+
+## Bringing your own project
+
+When you're ready to switch to your real dbt project, `cd` into it and run
+altimate-code again. The scan will pick up your `dbt_project.yml` and offer
+to connect its warehouse.
