+# Groceries
+An application for (manually) tracking your grocery shopping habits.
+
+## Installation
+A pre-built image is available at [ghcr.io/jamsch0/groceries](https://ghcr.io/jamsch0/groceries).
+The default configuration can be found in `config.ini` once the volume has been created.
+
+Example usage:
+```bash
+$ docker run -d -p 8080:80 -v ./groceries:/config ghcr.io/jamsch0/groceries
+```
+
+## Configuration
+Groceries uses a PostgreSQL database. The PostgreSQL connection is configured by setting the `Database` key in the config file:
+
+```ini
+# config.ini
+Database = "Host=127.0.0.1;Username=groceries;Password=password;Database=groceries"
+```
+
+The application will attempt to create the database if it doesn't already exist.
