-## Customize configuration
+## Installation
 
-See [Vite Configuration Reference](https://vitejs.dev/config/).
+To install this app, you need
 
-## Project Setup
+* npm, node.js
+* A PostgreSQL server, preferably on the local host (simpler)
+* basebox components (broker, dbproxy, bbc)
+* Keycloak
 
-```sh
-npm install
+### PostgreSQL Preparation
+
+You need to create a user and a database for the todo app. The recommended way to run basebox is to have a dedicated Unix user for dbproxy that authenticates to PostgreSQL using Peer authentication. This way, no password for the DB user has to be stored anywhere. The Unix user's name must match the name of the PostgreSQL user. For more info, see the basebox installation instructions and [PostgreSQL documentation](https://www.postgresql.org/docs/current/auth-peer.html).
+
+For simplicity's sake, we are using a normal PostgreSQL user that authenticates using md5 authentication, thus requires a password, which is set in the dbproxy configuration file.
+
+´´´sh
+# Under (Debian) Linux, switch to the postgres user first:
+# sudo su postgres
+createuser -DRP bb_todo  # default password: basebox
+createdb -O bb_todo bb_todo
 ```
 
-### Compile and Hot-Reload for Development
+Tell PostgreSQL that the `bb_todo` user connects to the database using md5 authentication. To do so, edit `/etc/postgresql/<PostgreSQL version>/main/pg_hba.conf` (on Debian based Linux systems) to contain the following:
 
-```sh
-npm run dev
+```conf
+# TYPE  DATABASE        USER            ADDRESS                 METHOD
+local   bb_todo         bb_todo                                 md5
 ```
 
-### Compile and Minify for Production
+Reload PostgreSQL config:
 
 ```sh
-npm run build
+systemctl postgresql reload
 ```
+
+If PostgreSQL is older than version 13, you need to enable the crypto extension explicitly:
+
+```sh
+# Under (Debian) Linux, switch to the postgres user first:
+# sudo su postgres
+psql bb_todo
+
+# At the # bb_todo prompt:
+SELECT gen_random_uuid();
+# If this prints a UUID, you're ok. If you get an error, do this:
+CREATE EXTENSION pgcrypto;
+# Might try the SELECT call again.
+```
+
+#### Database Schema
+
+This repository contains an already compiled SQL file that creates the database schema:
+
+```sh
+psql -U bb_todo bb_todo < bbconf/todo_datamodel.sql
+```
