+### DuckDB
+
+Lightdash supports DuckDB project connections through [MotherDuck](https://motherduck.com/).
+
+You can see more details in [dbt documentation](https://docs.getdbt.com/reference/resource-configs/duckdb-configs).
+
+##### Database
+
+This is your MotherDuck database name.
+
+For example, if your dbt profile uses `path: "md:analytics"`, the database value in Lightdash is `analytics`.
+
+##### Schema
+
+This is the schema in your MotherDuck database that Lightdash should use.
+
+##### Access token
+
+This is your MotherDuck access token. You can create one from your MotherDuck account settings.
+
+We recommend using a dedicated token for Lightdash with access only to the database(s) you want to query.
+
+##### Threads
+
+The number of threads dbt should use for this connection. If you're not sure what to use, start with `1`.
+
+##### Start of week
+
+This controls what day is the start of the week in Lightdash. `Auto` sets it to whatever the default is for your data warehouse. Or, you can customize it and select the day of the week from the drop-down menu. This will be taken into account when using 'WEEK' time interval in Lightdash.
+
+##### dbt version
+
+DuckDB connections in Lightdash require dbt `v1.8` or later.
+
+If you work with dbt locally, your `profiles.yml` should look similar to this:
+
+```yaml
+my-motherduck-db:
+  target: prod
+  outputs:
+    prod:
+      type: duckdb
+      path: "md:analytics"
+      schema: main
+      threads: 4
+      extensions:
+        - motherduck
+      settings:
+        motherduck_token: "{{ env_var('MOTHERDUCK_TOKEN') }}"
+```
