 Postgres backend
 ================
 
-Since version 1.3 Shillelagh ships with an experimental backend that uses Postgres instead of SQLite. The backend implements a custom [pyscopg2](https://pypi.org/project/psycopg2/) cursor that automatically registers a foreign data wrapper (FDW) whenever a supported table is accessed. It's based on the [multicorn2](http://multicorn2.org/) extension and Python package.

It's based on the [multicorn2](http://multicorn2.org/) extension and Python package.
 
 To use the backend you need to:

 If you want to play with it Shillelagh has a `docker-compose.yml` file that will run
 Postgres with the extension and the Python packages. Just run:
 
-    $ cd postgres/
-    $ docker compose up --build -d
+    $ docker compose -f postgres/docker-compose.yml up
 
 Then you can run this script.
